What he teaches
Chemistry by Vikram Sagar.
Organic Chemistry
Nomenclature, isomerism, GOC and reaction mechanisms — built up step by step, so a new question is not a new memory test.
JEE Main & Advanced
Chemistry for the JEE papers, with concepts first and plenty of problem practice.
NEET Chemistry
Chemistry for the NEET exam, with regular practice and tests.
CBSE Class 11–12
Chemistry for the Class 11 and 12 board exams, with clear notes.
How he teaches
Understand it. Then practise it.
Concept first
Every topic starts with why — the reason behind a reaction, not just the result.
Practice after every topic
ATC practice sheets for each chapter, with his feedback on mistakes.
Micro tests
Short tests that show what is strong and what needs one more round.
8 students, one table
Small enough that every student asks, answers and gets corrected.
