To secure a free seat in a B.Tech Biotechnology program, particularly for a "school category" (presumably meaning a reserved category like SC/ST/OBC), you'll need to meet the eligibility criteria and achieve a good score in relevant entrance exams like JEE Main or CUET, with a focus on securing a high percentile or rank, depending on the specific college and admission process.

Eligibility Criteria:

Class 12: You must have passed Class 12 with Physics, Chemistry, and Biology/Mathematics (PCMB) or Physics, Chemistry, and Biology (PCB).

Minimum Marks: A minimum aggregate of 50% (or 45% for reserved categories) in Class 12 is often required.

Entrance Exams: Admission to B.Tech Biotechnology programs, especially in top colleges, often requires a good score in entrance exams like JEE Main or CUET.

Entrance Exam Performance:

Target Score: Aim for a high percentile or rank in JEE Main or CUET to increase your chances of getting a seat in a good college.

Category-Wise Cutoff: Keep in mind that cutoffs vary based on the category (General, OBC, SC, ST, EWS).

College-Specific Cutoff: The cutoff marks for specific colleges and programs will vary, so research the cutoff trends of your target colleges.

Counselling and Seat Allotment:

JoSAA/CUET Counselling: After the entrance exam results, you'll need to participate in the counselling process (JoSAA for JEE Main, CUET for CUET).

Seat Allotment: Seats are allotted based on your rank/score in the entrance exam, category, and college preferences.

Free Seat:

Merit-Based Seats: Some colleges offer free seats based on merit, but these are usually limited, so a high score is crucial.

Reserved Category Seats: Reserved category seats are available for SC, ST, OBC, and EWS candidates.

Important Notes:

Research: Thoroughly research the eligibility criteria, entrance exams, and cutoff trends of your target colleges.

Prepare Well: Focus on your studies and prepare well for the entrance exams.

Stay Updated: Keep an eye on the official websites of the entrance exam authorities and the colleges for any updates or changes in the admission process.
