Hear what our students have to say

Throughout my 11th and 12th, Chandrajit sir has been an incredible teacher, a great guide and a person I alaways could and did approach to sort out any acadimic Doubts I had. No doubt that he has truly been in Instrumental in all my sucess in those 2 years, including clearing KVPY and the three NSES(Olympiads)

I am a student of Chandrajit Sir (CB Classes) enrolled for physics coaching for JEE-ADVANCED for the session 2012-14. I gave my entrances in 2014 and secured an air of 143 in JEE-ADVANCED and topped the WBJEE-2014. I owe a lot of my success to my decision to join CB Classes and Chandrajit Sir in particular. I joined his classes in april 2012 due to the past success stories in Kolkata and overall reputation. The classroom environment was competitive and yet promoted a flexible learning environment. Besides class hours, I got a lot of support in the form of extra material and even personalized doubt clearing. The best part was weekly tests - they helped me improve in terms of exam performance. The Main focus was underlying concepts and so his help was beneficial in boards as well as other exams. I learnt a lot in the classes as well as by interacting with Sir. I am deeply indebted to CB classes and would recommend Anyone serious for JEE to join it.

I joined physics class in CB Classes in 2017-18 for JEE Main/Advanced. The environment here is very competitive and interactive. The faculty is also very supportive, giving priority on making every concept lucid, clearing doubts and practicing maximum types of questions in classes. The study materials like CRTs, CPPs, Revision sets, etc provided for all topics provide to be very handy while going through concepts. Weekly tests and phase tests conducted helped me estimate my process in topics. I am grateful to CB Sir and CB Classes as a whole for helping me throughout my JEE preparation. Had it not been their guidance, it would have been impossible to crack these exams.

I joined CB Classes in class IX for my Boards Examination and secured 95.2% in ICSE. After that, I continued with CB Classes for my JEE preparation through class XI and XII. CB Classes played a very important part in my preparation. Concepts in all subjects were thoroughly explained. Oaried problems in good numbers covering different topics and ideas were given and guided to solve in every class. Moreover, there were weekly assignments, containing numerous problems for practice. Weekly tests were conducted so that we could evaluate ourselves and find our shortcomings. All teachers were always ready and available to clear any doubts that I had. Individual attention was given to each student. CB Classes also helped me to prepare for class 12th Boards by organizing Boards classes too. Without CB Classes my results would not have been possible.

CB Classes helped me a lot by bringing an organized and extraordinary coaching to the doorstep. Regular weekly tests helped us keep track of our process and carefully assembled assignments and fact sheets combined the best of various books. CB Sir himself is the best Physics teacher that I have come across. Chemistry and Biology classes were wonderful too. My teachers were really approachable and an online doubt clearing group was present to help us irrespective of the day and time. Phase tests held in the pattern of major exams like NEET and JEE were a blessing. Board support material and board pattern tests helped to cope with school and board exams. It is only because of CB Classes that I managed to secure AIR 3876 in NEET, 1535 in AIIMS, 588 in JIPMER and 815 in KVPY. Thank you CB Classes!

I joined CB Classes for Physics in Class XI (2015). I came to know about the Coaching Center from a senior student. I attended Chandrajit Sir's Classes throughout Class XI & XII. His teaching methodology has been very interesting and helped me understand the intricate concepts of physics. Doubt Clearing Sessions were no less effective. Library facility was of immense help. Daily assignments sheets (DAS) and weekly tests were equally useful. All combined, CB Classes boosted confidence to clear all competitive exams like NEET, AIIMS, JIPMER, WBJEE, JEE Main & Advanced and KVPY (SX). I am currently studying B.Sc (Research) in IISc., Bengaluru. I am truly thankful to CB Classes for helping me achieve my goal.

There are a few places where mediocrity can be destined to shine if instructions are followed religiously. CB Classes is such a guiding star. This comes from a mediocre student who would have been lost in an abyss but for the presence of the guiding star, both academically and mentally in the hallowed portals of CB Classes.

I won’t be over stating if I say all my achievements during +2 have been made possible directly or indirectly by CB Classes. The methodical teaching, emphasis on concepts & applying them, systematic exam, doubt – clearing sessions – all have been incredibly helpful both in writing exams and getting me interested in the game of science. Also a must-mention is the motivation and confidence given by CB sir to every single student individually. It is because of CB Sir and CB Classes, I am what I am today.
