Hi

hope you doing well

Your chances of getting CSE at SASTRA University with 91.4 percentile in JEE Mains and 84.6% in CBSE board are moderate but not guaranteed, as admission to SASTRA is highly competitive , especially for the CSE branch.

Sastra admission criteria depends on the more weight to your JEE Mains percentile (75%) and 12th grade percentage (25%) when preparing their merit list for admission.

As your 91.4 percentile in JEE Mains, you may still have a shot, but the exact chances depend on the overall applicant pool. If not CSE, you might get a seat in related branches like IT or ECE.
