Hi.

Unfortunately, NO. You cannot change your college preferences once the choices have been locked. If in Round 1 you have not been allotted a seat then you need to wait for Round 2 for seat allotment and round 3 and so on. To avoid this confusion, it is recommended that you fill your preferences in such a way that fulfils your college choice but also takes consideration of previous year's closing ranks.

Try to fill atleast 10-15 colleges and branches that you have the highest chance of getting into.

You can use our College Predictor tool for JEE Mains to help you in finding college and branch of your choice based on your merits in the exam.

Good Luck
