Hello Viraj,

Well SASTRA University takes admission through two streams - 

• Stream 1 : The candidates needs to have appeared JEE Mains and should have qualified 10+2 or equivalent exam marks. 70% of the seats will filled through stream 1.
• Stream 2 : The remaining 30% seats will be filled through candidates 10+2 or equivalent exam marks.

Now through these two streams a final merit list will be prepared by the authorities and on the bais of that list admissions will be done. So I would suggest to attend the counselling proccess for SASTRA and see which branches are you getting.

Hope that you get your choice of branch. Good Luck !!!
