abhi2807 General Eligibility Pass 10+2 or equivalent with Physics, Chemistry, and Mathematics (PCM). Minimum aggregate: 50–60% for most colleges. Top-tier institutions may require ~75% aggregate in Class 12. 1. Top-Tier Institutions (IITs, NITs, IIITs, GFTIs, etc.) JEE Main Eligibility At least 75% aggregate marks in Class 12 (General/OBC/EWS), or Be in the top 20 percentile of the respective board. SC/ST/PwD: 65% minimum or top 20 percentile. JEE Advanced (IITs) Same Class 12 thresholds as JEE Main: 75% (General) / 65% (SC/ST) or top 20 percentile. College-Specific Examples NIT Puducherry: 75% (General) / 65% (SC/ST) or top 20 percentile. NIT Raipur: Same eligibility rule as above. 2. Other Colleges (Private & State Engineering Colleges) Many private institutions admit students directly based on Class 12 marks (no national-level entrance). Typical eligibility: 50% aggregate in PCM (Physics, Chemistry, Mathematics). AICTE Guideline: Minimum 50% in PCM; relaxation to 45% for reserved categories. Examples VIT Vellore: 50–65% required. SRM Institute of Science and Technology: 50–60% required. BITS Pilani: Around 75% required (even among private colleges). 3. State-Level Entrance (Example: Assam CEE) General category: At least 50% in PCM + English combined. SC: At least 45%. ST: At least 40%.

For private colleges (direct admission): Usually 50% in PCM is enough, but top private ones (e.g., BITS Pilani) require higher marks. For state-level exams: Cut-offs vary by state; Assam CEE is one example with 50% PCM+English (General category).
