In Jipmer the most difficult subject is Biology(even Aakash and Allen books fail)
Only those who have read Trueman’s biology get good marks. On other hand Bio in NEET is damn easy.
Chemistry is slightly tougher than NEET.
Physics is same as NEET.
Overall it is somewhat tougher than NEET.
The main problem is there are around 200 seats and almost 1.5 lakh contestants.
I would recommend don’t fall for Jipmer i.e. don’t waste too much time in Bio (even it’s ranking is going down)
Hope it helps.
