For a Computer Science degree, the required percentage of marks in Class 12 typically falls within the range of 50-60%, with a science background (including Physics, Chemistry, and Mathematics).

Some institutions may require a minimum of 75% for general/OBC categories and 65% for SC/ST categories, especially for top-tier institutions like IITs and NITs.

There isn't a specific "percentage of marks" for Computer Science in JEE. Instead, JEE (both Main and Advanced) focuses on ranking and percentile scores.

To get into a good IIT for Computer Science, you'll need a high JEE Advanced rank, typically within the top few thousand, which corresponds to a score of 280-300+.

For JEE Main, a good percentile score (e.g., 90 percentile for General) can get you into good NITs or IIITs for CSE.
