How many marks are required to get admission in government engineering colleges?

It is not a fixed number. It depends upon several factors as rightly notified to you by @Deepak Gupta, and therefore instead of worrying about the minimum requirements one should focus on what maximum he/she can get.

Hi Mayank, Most colleges have a different provision for admission. You need to contact the institute officials personally for specific admission details as it differs from one college to another. Hope this information helps. Please feel free to revert. Wish you luck.
