With extensive experience in teaching biology, chemistry, and interdisciplinary subjects across a variety of educational systems, I offer a diverse and adaptable approach to learning. I have taught the NCERT curriculum, State Board syllabi, IGCSE, GCSE, IBDP (including Environmental Systems and Societies - ESS, and Theory of Knowledge - TOK), AS and A-Level, and AP Biology, providing a comprehensive understanding of these systems and how to effectively engage students. Whether you're looking for subject-specific guidance, exam preparation, or conceptual clarity, I tailor my lessons to meet individual needs and learning styles.

As an IBDP educator, I specialize in ESS, a unique course that integrates scientific, environmental, and social perspectives to address global sustainability challenges. I also guide students through the complexities of TOK, helping them explore the nature of knowledge and develop critical thinking skills that transcend traditional subject boundaries. My teaching approach emphasizes inquiry, reflection, and real-world applications, preparing students for both their exams and life beyond the classroom.

In addition to biology and chemistry, I offer expertise in high school-level science subjects, focusing on building strong foundational knowledge while encouraging analytical thinking and practical application of concepts. My lessons are designed to inspire curiosity, foster a deep understanding of scientific principles, and enhance problem-solving skills.

Whether you're aiming for top scores or seeking to deepen your understanding of environmental issues, interdisciplinary thinking, or science in general, I am dedicated to providing personalized guidance to help you succeed academically and intellectually.
