HELLO !BHANUPRATAP

Your expected gate score is close to cutoff score of old IITs for mtech programs under SC category.To secure IITs for mtech programs under SC category you need at least 420 score. With this score you may get NITs and other IITs expect older IITs.This cuttoff may be changed as it depends upon ranking of IITs and number of applicants seeking particular IITs.For sureity wait till,IIT madras declares score of Gate Exam.

You can ask if you have any other queries.

GOOD LUCK!
