Getting a CSE seat at SASTRA University, Tanjore, depends on a mix of your performance in JEE Main and your board marks (IP marks in your case). SASTRA uses a unique admission system with two streams: Stream 1 is based on 12th marks + JEE Main score (with a 50:50 weightage), and Stream 2 is based only on 12th marks. With a 91 percentile in JEE and 982 in IP , your chances under Stream 1 are fairly decent , especially for CSE in the second round or through slightly lower-preference choices like CSE in the second campus (Kumbakonam) or specialized CSE branches (like CSE with AI or IoT).

CSE is one of the most in-demand branches, and at SASTRA, the Tanjore main campus is especially competitive. In the first round, usually top scorers (like 98+ percentile JEE or 990+ in board) get it. But with your combo, you still have a realistic shot—particularly if the cutoffs dip a little this year. Also, don’t forget to apply under both streams to keep your chances open. If you don't get CSE initially, keep an eye on sliding options in later rounds. Sometimes students drop out after joining elsewhere, and you might get upgraded.

So yeah, you're on the edge, but definitely in the game . Just apply smartly and wait it out—you’ve got a solid shot at CSE or at least a closely related branch.
