Resonace coaching classes is superb for cracking JEE. Mains but not for advances level. Teacher faculty are also good for Jee mains .but level for JEE adcanced and teachers faculty did not match. So mainly students crack JEE mains . but some students can able for cracking JEE advanced .resonance sheets and study material not enough for cracking JEE. Advanced.its only sufficient for JEE mains . I suggest to join resonance those students who preparing only JEE mains . and not for JEE Advanced.
