Hi,

You can take drop as there JEE Mains allow upto 3 attempts. If you take partial drop then you have to do two tasks. The first is to prepare for JEE and the other is to balance college Engineering study. It could be quite hectic because Engineering itself is very time requiring course. If you can manage both Entrance preparation and Engineering Course then you should take partial drop.

I hope this will answer your query.

Thanks!!!!
