All of the reputed government institutions (IIT, NIT, IP, and other state universities) only given admission through entrance exams.

So, if you did not appear for any entrance then you have only one thing left with you ……. Private Colleges and Universities.

Well, all the private colleges and Universities are not bad. Some of them are been run for quite a time now and they have a good connection with the industry hence getting great placements. And be ready to study hard if you wanna get placed from a private college because you get placed in a core industry only if you are in the TOP 20% of the class (and ya obviously….. you are not in a government institution, so you have to be the best to get something which an average IITian or NITian would get after college).

Now coming to which college India would take admission on Board Marks !!!

Some private colleges have their own entrance like Manipal, VIT etc , but nearly all the private colleges give admission on Merit.

I can see that you have a great percentage in 12th board. A person needs great concepts and basics to get a score above 85% in 12th and universities know it.
