Vibrant Academy comes among the top coaching institutes for JEE in kota along with Resonance, Career Point, Bansal Classes and Allen. I opted for this institute when I dropped a year after my 12th std. While for 11th and 12th std, it is really a good option even for average students, for the drop year( the 13th std. as they say in kota;-)) its level is comparatively high and is recommended only for above average students. student should always try to be in the top batch which reshuffle after every second test. The teaching faculty comprises of some of the best teachers who have excellent command over their subjects. Almost every teacher in the top batches is either an IITian or NITian. Study Material provided is also good and sufficient to crack JEE examination if solved sincerely which contain important questions from every popular book. tests are conducted every two weeks and its level is also good challenging the student every time. Overall it is an excellent institute but only for those who are willing to put their 9-10 hours daily for hardwork.
Good Luck for those opting kota as their study centre. Cheers!
