Respected Sir,

This year the qualifying marks forinstrumentation branch for general in GATE 2017 is 34.2% and you have got 41.36 % in the year 2018 which is accordingly good score in GATE for instrumentation as you know you have just qualified in GATE because as you know the qualifying score will be nearby to 34.2% as of some upper and lower limits.

you can apply for some state government colleges or some good private colleges but i am really sorry to tell you sir that you won't get any good and top government colleges.

but,as i can see the data in the year 2017 18000-20000 students have appeared for GATE exam in instrumentation branch and qualifying score was 34.2.

so,may be you can get a state government college.

all the best
