Hello,

Achieving the required 75% in your Class 12 board exams is crucial for admission into IITs, NITs, IIITs, and other Centrally Funded Technical Institutions (CFTIs) through JEE Main. Given your situation, consider the following options:

1. Top 20 Percentile Criterion : If your aggregate marks place you in the top 20 percentile of your Goa Board, you may still be eligible for admission. Verify the specific percentile cut-off for your examination year.

2. Alternative Examinations : Explore enrolling in the National Institute of Open Schooling (NIOS) to retake your Class 12 subjects. NIOS provides opportunities to improve academic records, and its certifications are recognized for JEE Main eligibility.

3. Private Candidates : Investigate if the Goa Board allows you to appear as a private candidate for additional improvement exams beyond the usual attempts. This may provide another chance to enhance your scores.

4. State Engineering Colleges : Consider applying to state engineering colleges or private institutions that may have different eligibility criteria and might not strictly require the 75% threshold.

It's essential to consult the official JEE Main guidelines and the Goa Board's regulations to understand all available options and ensure compliance with their requirements.

Hope you find it useful !
