hi,

see the directorate of technical education kerala takes admission to m.tech course based on gate score. if seats are remain vacant then non gate students may apply and selection would be based on b.tech or engineering graduation course wise.

now see there is many exams held in India  apart from gate to get admission in m.tech courses. some of the exam you may try for beside gate is,

AP PGECET

IIITH PGEE

TS PGECET

Gujarat PGCET
