There is no such criteria ( minimum JEE marks) for admission in to SASTRA university . SASTRA university has a separate procedure through stream 1 and stream 2 Stream 1 .

70 percent seats of every branch are filled through stream 1 based on 12 th percentage ( 75 percent after normalisation ) + JEE mains score ( 25 percent )

For example

12 th percentage - 88 (CBSE) and JEE mains score is 80 .

Normalised percentage of board would be as follows

88 * 100/98.6 = 89.25

( Assuming percentage of topper is 98.6 )

Now 89.25 * 0.75 + 80 * 0.25 = 86.94

This is your final score . AIR (SASTRA) is prepared based on this final score . There is a chance AIR up to 4000 .

If someone is a topper of board exam and his JEE mains score is 40 then final score would be 85 and AIR (SASTRA) would be above 5000 . It proves that there is no chance for JEE mains score below 40 in stream 1 .

Stream 2 .

30 percent seats of every branch are filled through stream 2 based on 12 th percentage .

There is very less chance for percentage below 95 in stream 2
