B.A

It's technically impossible for a person to get directly into 3rd year after completing 12th.

Cut off for non-Christians (without arts) was 98.20% and non-Christians (with arts) was 92.48%. Keeping these numbers in mind, you might get admission in 1st or 2nd cut off because every year, percentage increases. Rest hope for the best. Best of luck.

Details about the subject course are not available on their official website. You can mail them your query on this email address:

Hello,
Likitha Migration is possible only within universities after the completion of first year only with lots of paperwork to be done.
You will need various documents from both the college you are in and from the college you aspire to get in.
It is possible but it will be advisable to start again if you want to change your university.
Moreover, you need to search the procedure of migration of your college and the college you want to go in as different colleges have different procedures.
All the best.
