B.Tech

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 thatthere 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 .

Hello Raghul R, no, Sastra deemed to be university does not prescribe any cutoff for admission. What this means is that a student with any percentage or any ranking can see admission by applying. Of course it's different story whether such student will get admission or not because it depends on the number of seats available and number of students who have applied. To help you gain knowledge further I am attaching a link that you give you all the required information about admission to engineering in Sastra deemed to be university.

Hi Ansh, I would like to let you know that many colleges and universities have their eligibility criteria as the students should have PCM as their main subject in their 10+2. As per the eligibility and qualification criteria of B.Tech courses it is a bit difficult for you to apply for this course in any of the government college. But, some of the private colleges may offer this course to PCB students but that too at a very high cost, like LPU (Lovely Professional University) allows PCB students to pursue B.Tech in computer Science despite mathematics not being your main subject in 10+2. But, you have to appear in the entrance exam conducted by the University and qualify that as per their eligibility criteria. There are other private universities which give admission on the basis of their entrance exams. Some of the colleges are SRM University, KIIT, Manipal, etc. But I would like to advice and suggest you to look for courses in PCB field too. You will find a plenty of courses regarding this stream and there's a huge scope in it also. Because it will be very difficult fir a Biology student to cope with mathematics until and unless you don't have a large interest in that and you are too good in mathematics. If you have had mathematics also as a major subject in your intermediate then you can apply for JEE Mains examination allows large number of candidates to pursue engineering courses from their dream government colleges. Hope it helps. All the best.
