hi,

see there is several colleges which offer m.tech course based on tancet score. also it depends on which stream you want to join m.tech. some of the tier 1 college which offer m.tech course based on tancet,

anna university

PSG College of Technology

SRM Institute of Science and Technology

Madras Institute of Technology

SSN College of Engineering (SSNCE)

Coimbatore Institute Of Technology

College of Engineering Guindy, Anna University

Chennai Institute of Technology

but at this score you have less chances to get admission in tier 1 colleges under tancet score.
