Hi

There are two streams of counselling to get into SASTRA University. 70% of the seats are allocated in stream 1 in which 25% weightage is for JEE Main score and 75% weightage is for board marks. In stream 2, only 12th board marks are considered. Since you are JEE Main percentile is very low and board percentile is much below 95%, getting a seat in SASTRA University will be very difficult.

Hope this helps.

Cheers!
