I'm in my fresh year of engineering college,so I feel that I can guide u well…….

If u r expecting 100 then u cannot pave ur way through big colleges…such as VJTI ,SPCE ,KJSomaiya etc.U can apply through quota or switch on to colleges such as:

1.Vartak(Renowned for instrumentation and mechanical engineering.)

2.Thakur(EXTC might happen.)

3.Francis(IT or EXTC.)

These are some good colleges for a 100 score.

Or else try filling institute level forms for some colleges,might be u get a seat and fit in.
