Admission in Fergusson College is on the basis of merit. With this percentage, there are 50-50 chances that you'll get admission. Also, it depends on the category you belong to. Previous year cut-off are not available on the official website, but because I had applied for the same last year, I know that you might get the admission because my percentage was 87 and I could not make it.
I hope you get the admission.
All the best.

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.

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.
