Hi aspirant

Its very difficult for you to get decent college .Most probably you will get GFTIs of your state otherwise state engineering  college.You may apply there.

You can check the previous year cut off of NITs and IIITs and GFTIs .Hardly you are upto the mark.

If its possible then prepare for the next year or apply at state engineering colleges/Universities.
