Hi A Rajani,

Congratulations on admission in TIET. Thapar conducts Online counselling based on JEE mains marks and then spot rounds take place at the campus auditorium. Where in also, the students are eligible for a branch on the basis of their ranks or percentile. It is not certain that if it will consider another spot round. But another counselling round takes place after the completion of First semester where they conduct a JEE mains type test internaly for the new admissions or the late admissions. The marks obtained in those are considered in the counselling which takes place just after the results are announced. So their is a pretty good chance that you will get a branch upgradation, but if by chance it fails to happen as wished, then after the completion of first year you will again get a chance to upgrade your branch. Although this round is purely based on the Cummulative Grade point Average,  but mostly everyone gets the upgradation, which the student wants. 

I hope your doubt will be cleared by this answer,

If you have any other queries then feel free to put it up on the portal.

Thank you
