Hello dear..

It's very difficult to get best college with these score.
For Mech and civil it's very very difficult 
If u r thinking for comp it entc branch then you might get descent college
May b DY Patil, JSPM, and Sinhgad kondhawa these are also good colleges 
Go through CAP rounds .


If you can take risk then wait for 2nd, 3rd round . 
One of my friend who also had a almost 75 marks got very good college but he waited for 4th round. But it's very risky to wait for 4th round so take decision on your own risk.
Best luck.

Edit : there is one more way to get good college even if you have low marks I.e. NFR (no fee refundable) through this quota you won't be able to get any scholarship example  EBC . So very few student apply through this quota .but you have to pay full fee. You can take more information about this through the ARC centre. (There are some conditions to take admission through NFR ).

Best of luck..
