Hey Singht,

To get admission at CVR you need to score min 75 in TS eamcet

It doesn't base on the marks you get but on the rank you have achieved in the EAMCET rank.

If we look at the last year cut off and last rank statements for CSE the last rank is 4674 and it is been varing department to department and year to year

Above link will give you a detailed idea of all the colleges cutoff and last rank statements in the TELANGANA  during 2017.

Most probably every year the cutoff's will be same as the previous year's rank or may differ by 30 to 50 ranks

so once you take a brief look into that url so that you will get an idea.

All the Best..!
