13 Reviews

The AMMOC Math Circle, Yaashaa Praveen Golovanov Sir welcomed me in January 2024. Since then, I've been going to class for three hours every day, and I've been studying geometry, algebra, combinatorics, and number theory—the four most important areas of mathematics—for the past three months with Sir Yaashaa Praveen. Based on my extensive experience and understanding, I can state with confidence that Yaashaa Praveen Sir's approach, his capacity to elucidate proofs of classical theorems of stated branches of mathematics in a clear and concise manner, and his demeanour towards students not only impart mathematical knowledge to us but also instill a love for the subject, inspiring us to pursue our studies in this fascinating area. Due to his INTENSE and RIGOROUS PROOF THEORETIC LESSONS, I was awarded
• a HONOURABLE MENTION in each of the subjects of geometry and algebra separately, and • an additional HONOURABLE MENTION in the 'Power Round' for our AMMOC Team in the STANFORD MATHEMATICS TOURNAMENT, which was organized by the STANFORD UNIVERSITY, one of the TOP Universities in the world.
Along with all of this, I would strongly advise everyone who enjoys math to enroll in Yaashaa Praveen Sir's truly deep & proof theoretic classes at his genuinely advanced and premier math circle - Arnold & Marsden Mathematical Circle (AMMOC), to get ready for exams like IMO, EGMO, APMO, AIME, USAMO, AMC, and UKMT.

Mr. Yaashaa Praveen Golovanov has been a mentor for my daughter since May 2023. My daughter started as his student, at his AMMOC Circle, after her 10th grade, where she missed qualifying for the AMC10.
WITHIN A SPAN OF 5-6 MONTHS, Mr. Golovanov pushed her math skill and helped her qualify for
• AIME, through AMC 12, during her 11th grade.
• Distinction in Australian Math Contest
In addition to just helping the student with Mathematics, he has been an amazing mentor, providing guidance and assistance to plan for my daughter’s college as we head to pursue her college goals in the next year. He urges students to push themselves and find new limits in their thoughts and capabilities. He has huge list of contests (American, Canadian, European, Asian) in which he pushes each student to participate.

• We feel honored and blessed to have Mr. Golovanov as a mentor, guide and teacher for our daughter.
Mr. Yaashaa Praveen Golovanov is an honored teacher with dedication and commitment. He has started his math circle - AMMOC in pursuit to create great engineers, mathematicians, and scientists of the future.
PS - assignments are regular and mandatory for submission. Each class happen in a GROUP of students (in single digit). Many parents want one-to-one attention, however, it’s a highly structured group of mathematically equivalent student who come to attend the class.
• My daughter is not only one who has improved her math so well at AMMOC, each student has same success story and qualifying to AMC 8,10,12. We have a parent group in which we can see the level of ENTHUSIASM & PRIDE each parent has about their child being a student of Yaashaa Golovanov.
• IT IS A VERY RIGOROUS & USSR STYLE math circle and if you get a chance to be part of his select circle, please don’t hesitate and you should consider to join him. He has over half students from US and Canada. Others are from Europe and India.

My son began his journey with Yaashaa Praveen as his tutor approximately 8 months ago, and the transformation in his Maths skills since then has been NOTABLY COMMENDABLE with following achievements under guidance & teaching of Yaashaa Praveen -
• Gold Honour/Medal in premier IMC - contest of UKMT and further invitation to participate in the prestigious CAYLEY MATHEMATICAL OLYMPIAD of UKMT.
• 16/25 in AMC 8.
• Performance with Honours” in Canadian Jay Mathematics Contest - CJMC (2023) - a flagship contest of the Canadian Mathematical Society.
• High distinction in Australian Mathematics Contest for being in top 2.5 %
• Being in Top 5% in the Canadian Caribou contests supported by Canadian Mathematical Society & The Fields Institute
It's evident that Yaashaa Praveen harbors a deep passion for Maths and this enthusiasm translates into his teaching and pedagogical methods at his now a premier Math Circle - AMMOC.
He consistently pushes the students to reach their highest potential, ensuring they are well-prepared and confident. The curriculum he has adopted is strategically tailored and has quintessential reflection of USSR and Eastern European approach to mathematical education leading to SUCCESFULL PREPARATION towards SEVERAL PREMIER INTERNATIONAL MATHEMATICS COMPETETIONS from USA (AMC, AIME, HMMT, USAMO), UK (UKMT's JMC-IMC-SMC), CANADA (CMO, COMC, CEMC contests), RUSSIA (Geometry Olympiad) and ASIA. His recommendation for the students to participate in one exam per month has been fruitful, as it's evident in the OUTSTANDING RESULTS ACHIEVED by not just few, rather BY ALL OF HIS MENTEES under his guidance. My son, Tommy, thoroughly enjoys each session with Yaashaa Praveen, even though the challenges presented are often of high complexity. Yaashaa Praveen embodies everything one hopes for in an EXCEPTIONAL TEACHER, MENTOR, and INSPIRER with a profound understanding of the Mathematics paired with immense passion. I WHOLEHEARTEDLY RECOMMEND to join him and his rigorous & structured program - AMMOC Circle.

Mr Praveen has been nurturing my daughter Deepa for more than 6 months coaching her in proof based mathematics in the area of Algebra, Combinatorics, Euclidean geometry and Number Theory.
The classes are intense with importance given to daily assignments where the effort and intent of the kid to complete the assignment is weighted more than the results of assignment problems. Since his mentoring process has already been trail and tested backed by solid results it easy as a parent to just follow his schedule and plan with complete confidence.

ON MATHEMATICAL LEARNING—
I have been learning Olympiad mathematics with Mr. Yaashaa Praveen since May 7, 2022. With him, in his selective class of mathematically inclined students, I learnt art of proofs in mathematics using mathematical induction, proof by contradiction in theorems related with INTEGERS POLYNOMIALS, MASS POINT GEOMETRY, CEVA, MENELAUS, EISENSTEIN’s IRREDUCIBILITY criterion, BASIC COMBINATORICS, MID POINT THEOREMs. We did triangle geometry at good depth including trigonometric solutions to triangle. In all these topics, after proof of each theorem, we studied concrete application on problems of mathematical contests like AMC 10, 12, AIME, EUCLID, FERMAT, HYPATIA, CHIENSE, HUNGARIAN, BULGARIAN, ROMANIAN and other contests. Assignments are very challenging, and submission of them is strict policy otherwise he would cancel class if student fail to submit assignments. He encourages asking questions during class and repeatedly checks on each student to see if they are understanding the topics. The course rigor helps to do well in the subject.

—RESULTS in MATHEMATICAL CONTESTS—
He introduced me to the Canadian Math Contests and I brought it up to my school math team. It benefited our school's math team students. Under his Mentorship and teaching I was qualified to write AIME by making the AMC12 cutoff. I won DISTINCTION in FERMAT contest of UNIVERSITY OF WATERLOO. I hope to learn lot more mathematics in coming months with Mr. Yaashaa G. Praveen. My math concepts and skills have improved tremendously in the short span and has given me confidence to self study.

Yaashaa Praveen Sir’s educational “AMMOC Math Circle” has been one of the most academically challenging, advanced yet rewarding program that both I & MY PARENTS have seen. Review Updated Feb 2024.
---JOINED on April 19, 2021 & continuing so far with following OUTCOMES---
• Distinction & International Honour by U. of WATERLOO for
1. Proof theoretic FRYER Contest, June 2023
2. Objective AMC 10 level Pascal Contest, 2023
3. Subjective CIMC Contest at AMC 10 level, 2024
4. AVAGADRO Chemistry Contest, 2023.
Performance in Contests of Canadian Mathematical Society
1. Performance with Honours in Canadian Open Mathematics Challenge (COMC) – The most prestigious Olympiad of Canada leading to invitation at CMO and further in IMO. This is of same difficulty level as AMC 12.
2. Performance with Honours in prestigious “CLMC” contest of CANADIAN MATHEMATICAL SOCIETY.
3. In top 3 % in the WORLD, with rank 111 out of 4220 participants worldwide in premier CANADIAN CARIBOU contest.
Performance in Australian Mathematics Contest and Asian Contest
1. “Award of CREDIT” in AUSTRALIAN Math Contest.
2. More than 20, Silver/Gold/Bronze Honours in Various international contest in the south Asia.

--Rigor, Teaching style & Evaluation--
He is a professional mathematician and scientist. His teaching reflects
• His passion to impart his in-depth knowledge to new generation
• Clear statement of DEFINITIONS, THEOREMS with PROOFS & EXAMPLES FROM PAST CONTESTS.
• You can LITERALLY ASK any DOUBTS
• Discussion of past RUSSIAN, GERMAN, BALKAN, BRITISH, CHINESE, SINGAPORE, AMC, AIME, COMC, MATHCOUNTS, USAMO, CANADIAN, & ROMANIAN contest papers.
• In discussions of doubts, he recalls all necessary definitions & theorems repeatedly. It is time-consuming yet extremely rewarding.
• It takes time to realise how your approach towards the subject & problems given is changing. Alongside that, results shall also appear later like in my case. I have seen how he has nurtured three seniors with daily lecture for two years -
•I am slow learner and in these last 2.5 years I have learnt real hard stuff in Mathematics which are not taught anywhere otherwise. Give yourself a time of AT LEAST ONE YEAR & you will witness remarkable growth in your abilities.

Review of Arnold-Marsden Institute of Mathematical Olympiad:-
In this Program Yaashaa Praveen has three objectives -
1. To teach mathematics to students as ``science of logical deduction``. Each Course begins with all prerequisite so that every participant follows up the lecture regardless of his or her background. Also, throughout lectures he keeps recalling definitions, theorems and if necessary even theirs proofs which he taught us previously. This helps us to develop intuition as we relearn things from him.
2. The courses though start at very scratch say at level of competition likes AMC 8, AMC 10, PASCAL, FRYER, GALOIS, GAUSS, UKMT [IMC, SMC] wherein he proves every elementary theorem that one encounters till his grade 10 in his/her studies of mathematics and then he discusses past papers of these prestigious junior mathematical Olympiads. Those who qualify these exams are then prepared for Second Tier national exams AMC 12, AIME 12, and like COMC, FERMAT, EUCLID, HYPATIA, CSMC of university of waterloo. Courses are divided in Levels like ALGEBRA1, 2, 3, Geometry 1, 2, 3, Number theory 1, 2, 3, Combinatorics 1, 2, 3. So, there is no danger of student finding any course difficult. Of course, there is too much of freedom to ask any doubts that you have. Third part becomes incredibly hard, substantially rigorous and a gives student a feeling of a truly aspiring young mathematician and is only for those who have qualified multiple exams at second part of course. I studied DIOPHANTINE EQUATION as third part of number theory. I can tell you that his lectures on third part of NUMBER THEORY, COMBINATORICS, ALGEBRA, GEOMETRY are parallel to standards like in undergraduate program of top American, Canadian, and European Institute of Higher Mathematics. For third part he uses books which are used in undergraduate courses of HARVARD, MIT, BERKLEY, PRINCETON, STANFORD. For examples, Yaashaa Praveen uses books of Richard Bruladi [professor of University of WISCONSIN] Michael Th. Rassias [PhD from Princeton and Faculty at ETH in zurich], is former mathematician of Princeton now at ETH in ZURICH, Alexander Gievental [ leading mathematician of UNIVERSITY OF BERKLEY]. Books of these mathematicians are recommended even on official IMO website. To my knowledge, those who have attended level 3 of his courses, like Konstantinos Charalambous, Adelina, Gyani Tisya, have qualified in IMO, EGMO, COMC, EUCLID, CSMC, IOQM, AMC, AIME, and have won FELLOWSHIPS to study in

----Remark – This REVIEW was UPDATED in OCTOBER 2023----
----My son Sarthak joined Yaashaa Praveen Sir 3 years before in October 2020 & continuing ----
With THREE YEARS of CONTINUED learning, MATHEMATICAL ACHIEVEMENTS of my son are (you can verify these data on his LinkedIn profile)-

----The MISSION & VISION Golovanov Sir for his proteges -----
• is to make them scholastic in mathematics & science
• to prepare and help them to obtain FULL SCHOLARSHIPS like following three of his longer-term mentees received –
• *TISYA Rawat at California Institute of Technology CALTECH, UG, class of 2027
• *KONSTANTINOS Charalampous at U of CHICAGO, UG in Math, class of 2027
• *ADELINA Patlatii at U of Toronto, UG in Math & CS, class of 2026
• To continue to teach them UG mathematics & Physics
• To invite students to meet him and introduce his mentees to top professional Mathematicians & physicist in India, USA, UK, Russia & Canada.
• Discuss theoretical contents and problems of uncommon difficulty level that can challenge the ingenuity of any research mathematician.
• To provide early career research opportunities and teach undergraduate courses LINEAR ALGEBRA, GROUP, RINGS, FIELDS, GALOIS THEORY, DIFFERENTIAL GEOMETRY & TOPOLOGY in highly accessible way to his high school proteges.
• He INVITED me to his HOME & cancelled classes for a week for all his mentees so that he could spend time with me, and counselled me about the next two years of my mathematical & scientific journey with him (till 2025). NO ONE CARES THE WAY HE CARES for his protégés.
-----It is rarest opportunity that you can find to learn with a TRUE SCIENTIST & MATHEMATICIAN of his STATURE. Join him-----

The aim of this program is to teach habit of systematics thinking about a mathematical problems using axiom, definitions , theorems and theirs proof. When my child Mr Prathik joined this programme he was average into mathematics, which generally is case with most because ours EDUCATION SYSTEM TEACHES ONLY FACTS AND NOT THE REASONS BEHIND THOSE SCIENTIFIC FACTS.
This program FILLS this gap exactly.
When a child learns how to figure out which statement is a definition of an object , say circle , and which statement related to circle is not the definition of circle , it just ignites his brain and quest for investigation the necessary aspects of “defining a concept “.
At this age , if a child learns
1. how to formulate definition,
2. isolate hypothesis from claim of a theorem ,
3. to learn implications of a mathematical statement ,
4. when one mathematical statement is equivalent to other mathematical statement,
5. How to solve a problem purely using definition and then searching alternate solutions using theorems and not purely by definition
Then you know in what direction you’re child is heading to . Even a very average child sees significant growth into his critical intellectual abilities in span of six months . Over dozen of students have won performance of distinction in olympiads like AMC, Fermat , SEAMO, IOQM, EGMO, IMO. This teacher is a scientific researcher. So the program is highly pedagogy.
His courses are all divided like below
AG1. Algebra one that covers algebra from class 6-8
GE1. That covers geometry from class 6-8
NT1. Number theory of integers primarily
He teaches graph theory , combinatorics , geometry number theory to 8th-10th grader in a way that they can easily solve AMC 10 problems very well . And yes after this IIT exam shall be a just a smooth transition with concepts.

He believes that every problems is special case of a general theorem and so study , analysis and proof of theorems is central piece of his teaching . Then Yaashaa Praveen Sir applies those theorems to study problems of Olympiad.
He teaches mathematics, physics and chemistry all with same objective “with understanding of theory one can solve any problems at competitive Olympiad and IIT “.

In March 2022, I was in search of a teacher who can prepare my son Darsan Sivakumar for Mathematics Olympiads of USA, UK, CANADA, AUSTRALIA, HONG KONG, SINGAPORE, INDIA. My son joined Yaashaa Golovanov’s AMMOC online Olympiad preparation program in April 2022 (at start of his 7th grade then).
••OUTCOMES after 16 months of learning (and continuing)••
1. GOLD MEDAL in Junior Mathematics Challenge of UKMT, 2023.
2. DISTINCTION with INTERNATIONAL HONOUR in prestigious international math contests FRYER [30/40]. FRYER is organized UNIVERSITY OF WATERLOO and is mathematically equivalent to AMC 10.
3. DISTINCTION in GAUSS mathematics Contest of University of Waterloo [121/150]. Cut-off for distinction was 116 and I scored 121, in Gauss (mathematically harder than AMC 8).
4. BRONZE MEDAL in National round of Singapore and Asian Schools Mathematics Olympiad (SASMO)
5. BRONZE MEDAL in Individual round of Singapore International Mathematics Olympiad Challenge (SIMOC) held at National University of Singapore (NUS) during 22 – 24, 2023.
6. BRONZE Medal in Team Round of SIMOC held at NUS, 22- 24 July, 2023.

He is now in 8th grade. However, his syllabus for AMC 10 is already over. He is currently doing past papers of national and international math contests.

Very Impressive style of teaching which induces kids to the fundamentals of physics wherein complete emphasis is given to
1) explain and define the concepts very well . 2) Using definition, through application tools of calculus , vector algebra , trigonometry to prove results in physics
3) To let student to attend problems on theirs own .
Unless student exhaust his or her mental faculty , the hints are not given . Eventually through hints student yields solutions .
This continues for all section with 3-4 problems per class and with 5-8 probelm a as home assignments after each class in case if class is on daily basis.
Class resumes with discussion of doubts .
Whenever a new concepts is to be defined he makes student to think of a possible definition. Student invest few minutes to think about the possible definition before Yaashaa Praveen Sir gives actual definition. The need of those words in each definition is carefully explained. After definition , follows up some results(mathematical proof) and subsequent problems solving .
At the end of each chapter 42 years PAST PAPERS OF IIT ASVANCED are mostly solved by student on his/her.

So it is student driven programme.

Since it is student who takes efforts to apply definition and mathematical results in solving problems , so the speed is moderate and this is biggest strength of this program.
This also makes it clear that he doesn’t offer you a short term course. In very rare case he admits a student of class 12th. Generally student with time period around 12 months are only who get chance to learn from him IIT MATHEMATICS AND PHYSICS.
He teaches and have won several medals for his students in MATHEMATICAL OLYMPIAD as well .

In mathematics, he stick to principles “ no statement shall be written on board whose proof can’t be discussed in class”. So you would learn everything first as proof , then application on problems from classical Russian Books , EVENTUALLY ENABLING STUDENT TO SOLVE PAST 40 YEARS PAPERS of IIT advanced and Mains in his/her own. Any one who joins him would witness it moment he closes any one chapters.

He doesn’t teaches one to one . It is in group of 4-8 students . But he keeps a cap that maximum number of student in any group should not exceed single digit (maximum 9)
Reads yours assignments, corrects them, takes any and every doubts in class . If you don’t ask doubts you stand less chance to survive in his programme.
He expects children of std 8-11th to b

Truly excited to give a review on Mr. Praveen Yaasha sir. My son is fortunate that we could find this extra ordinary teacher, mentor. My child is in 12th and will be appearing for his JEE exams in the coming examinations. We have been taking efforts to join him for a good mentorship and my son doesn't show interest to learn from COACHING INSTITUTIONS ,WHERE THEY FEED JUST PURE FACTS WOTHOUT GIVING ANY REASON OR PROOF.
We as parents were particular that he should get good education with proper reasons behind things in his course and should be able to face entrance examination.
Since June 2021 he is under able guidance of Mr. Praveen Yaasha, and learning Physics and Mathematics. He teaches everything like a discussion forums , he gives time to student to think about each definition/theorems/problems before he gives them first hint , se one hint and final solutions.

My son solves every problems of JEE mains /AIEEE and advanced at last when each chapter is closed . Most of the time he solves almost 85-90% of the PAST mains and ADVANCED problems on his own easily.

He checks up all assignments, speaks at very personal level to each student, motivate them towards higher education. He could learn many new things with clarity and depth on concepts.

He also insists and encourage my son to join Olympiad and other national and international exams

We could see a remarkable change in my son’s progress and he attend the classes with more interest. We are sure that With Praveen sir’s guidance my son will make to a Great institution for his under graduate education , and we strongly recommend to the parents that it is a great opportunity which is rare , the parents should not miss.

He educate kids for physics mathematics for IIT and Olympiad as well .

His course runs at moderate pace and doesn’t takes for short term crash course . He would only take student if student has at least around an year to learn from him .

I hope parents do read it to find a suitable mentor, in Yaashaa Praveen Sir , for theirs child .

After the first lesson, Praveen understood well the student and knew what methods to apply to close the gaps and assure a steady and reliable growth to achive the desired goals. He uses good resources (books, papers, solutions) and also provides his notes (in written) after each lesson.
We recommend Praveen as a highly professional Math teacher for advanced mathematics.
