Very knowledgeable and very honest with his work

I got help in an advanced statistics subject. He was very responsive and honest, he agreed to a short discussion on a question for me to make sure he knows the material (most tutors on here wouldn’t) and was incredibly clear about everything. His price is very reasonable for the excellent service he provides, would certainly contact him again for anything I need.

Patient Tutor

He was patient and knowledgeable. Although the topic was pretty hard, he provided me a summary for the overview and helped me a lot.
He was quite flexible with scheduling a lesson such as online lesson or using chat and always reachable which I really appreciate it.
