which Institute is honestly the best institute for iit-jee preparation in India?
Super 30 obviously is the most well known of Bihar. Then comes is KOTA RAJASTHAN of course. Also on the list are ALLEN, PACE, FITJEE, etc coaching institutions. But what I'll suggest you is coaching classes is just a path wherein you've to walk and reach your goal. So if you are dedicated enough and focused enough then any of the coaching classes will help you achieve your goal.
Thank you.
