I think Resonance, Agra is the best place in Agra to prepare for JEE. I myself did my preparation there and I am not saying this because of that only.

I myself studied from Resonance, Agra for my JEE preparation and got AIR 2680. I can assure you that the faculties there are excellent, are very committed towards their job, and have a very strong hold of the subject.

RAV sir teaches maths there and believe me, you will never get bored in his class nor will you ever feel depressed throughout your tenure, no matter how badly you performed in your tests or whatever it may be. He will give you many fundas on everything, and to be honest, just do what he says, and believe that what he is saying is right. I am proof of that myself.

Sudhesh sir teaches Physics and the knowledge and teaching skills that he possesses are unmatched. His way of teaching is different from what students are generally familiar with but once you get used to his way, you won’t find difficulties in solving problems. Though you can solve each and every problem from his methods, but he still focuses on making the student understand the concept better.

Rajesh Arora sir teaches inorganic and organic chemistry and just like Sudhesh sir, he has very vast knowledge of his subject. He makes things that seems horrifying looks so simple and easy. He don’t believe in using shortcuts and tricks to remember concepts of organic chemistry, but if someone sincerely listen and understand what he teaches and practice questions, there is no need to use those shortcuts and tricks.

But no matter how good the study material is, or how excellent the faculty is, if you don’t study, you won’t clear JEE.

Hope this answer helps
