Hi

Thanks for your question,

It is very difficult to predict whether you will be getting admission in SASTRA UNIVERSITY with CSE branch or not.I would suggest you to use JEE MAINcollege predictor to know your chances in SASTRA as per your rank.Below i am sending you the link please go through it:-

Coming back to your question i think yes you can get SASTRA with Cse branch.Getting CSE is little bit difficult.Do give a try. 

Hope this was helpful.

Good-Luck!!!!
