This is totally your decision. If you think that taking a drop this year will land you in a better position than now, surely go for it. But if you doubt that you will not be able to get in a better position than this even after one year, I would suggest that do not go for it. These days college really matters a little. Yes IITs and NITs do, but only to an extent. Prepare as much as you can for upcoming JEE.
Good luck!

It can be good if you engage yourself in some internship while preparing for your entrances for the next year
