Dear aspirant,

As you have mentioned that you have got 78.34 percentile in jee mains and you are wanting to take up cs or ece in government college( NiTs/gfti's), so let me tell you in this percentile your rank would be somewhat around 2L-2.2L as per my knowledge. But it may various depending upon certain conditions such as:-

1-Number of candidates appearing in the examination.

2-Number of vacant seats in college.

3-Previous years cut offs.

4-Difficulty level of the paper

So , if I consider your predicted rank and you are from general category then it is impossible for you to get cse branch. For cse ,you need to score atleast 98.5+ to get into a good nit or gfti.
