Hello Aatif raza

With 77 marks you might be getting a rank around 25K-27K. with this rank you will get many good/decent colleges in mysore bangalore and mangalore But not top 10 colleges. for top 10 colleges you will have to compromise with the branch.

For example : if Bangalore in concerned then you might get:  Acharya-ECE, BNMIT, Christ, Jain, SJC etc etc etc.

If Mangalore in concerned then you might get: NMAMIT, ALva, MIET etc

And you might land onto some of the very good colleges too like SIT Tumkur, DSCE but you will have to make a compromise with the branch. So, getting CSE & ECE in top colleges is quite tough and almsot not possible with this score but you may try for Instrumentation in colleges like SIT, Tumkur.

Hope that helps!
