For admission to the M.Tech Biotechnology program at IIT Madras under the General category, candidates usually need a good GATE rank and score. Based on recent trends, the cutoff score has generally been in the range of 550 to 600 or above . In some years, the closing score has gone higher, depending on the number of applicants and seat availability. To be on the safer side, a GATE score of around 650+ is considered competitive for securing admission.

For M.Tech in Biotechnology at IIT Madras (General category), the GATE Biotechnology score generally needs to be around 700–800 based on previous years’ cutoffs. The exact cutoff varies each year depending on applicants, difficulty, and seats. I’ll be attaching the official link from Careers360 for detailed cutoff and admission information.
