Hi,

You have not mentioned your category so I will be answering from the perspective of a general student. The cutoff for CSE in round 3 for CCMT-22  was 683 CSE and 622 for information security in NIT Suratkhal and for NIT Trichy cutoff for round 3 CSE was around 700. So you don't have many chances. Meanwhile, you can use the GATE College predictor to find your best chances:
