if we talk about DTU (Delhi Technological University) — you must have at least 60% in PCM and pass all subjects. The 75% rule is not strictly applicable here, so you can get admission based on your JEE Main rank and Delhi quota, if applicable.

For IIIT Hyderabad, admission is based on JEE Main percentile/rank, but the institute also requires a minimum of 60% in Class 12 (PCM). So, even with less than 75%, you are eligible if you meet this 60% requirement.

Hope you understand. ALL THE BEST.
