The 3 years I studied under Raju sir, my maths skills have improved dramatically. He not only teaches topics from the book, but a lot of extra content as well. He stresses more on problem solving which is very important in maths. The main strong point is that he truly cares for his students and clears all your doubts. Even if the doubts are silly, he makes sure they are cleared.
Most importantly, he made me enjoy the subject to the extent that I decided to pursue Mathematics as my mainstream in classes 11 and 12. Sincerely thank Raju sir for all his efforts. Very strongly recommend learning under Raju sir.
