Hii archana! You are having a doubt of either dropping the jee mains.if your very much concerned to be held up into iit mains for getting nit you can obviously spare the whole day for it and get through the coaching for it.if you are worried of wasting your time then you can get through the college and you can have your studies and  jee mains on the parallel day by day.it might give you a better satisfaction.all the best!!

A good college is important, but preforming good in whatever college you are and working hard there is more important. I suggest you do not take a drop again, take admission now and focus on improving your skills there. Do not be disheartened because maybe there is something else in store for you.

Hello

If you are not interested in dropping another year then don't. You can do more productive in other colleges as well. It's not all about JEE Mains. Just try your level best this year. Do give bitsat examination as it is much easier than JEE mains and is equivalent to IITs.
