Hello Rohan.

Hope you are doing well.

As your rank is 46000 you have a very little chance of getting Computer Science seat in Government College. But you can go for Aided colleges. Even they have less fees when compared to the private colleges.

You kindly check this link so that you can get more information on the cutoff of previous year:

You can also go through this link to know your predicted college so that you get some idea on allocation of colleges

Hope this was of some help.

Good Luck!!!
