Hello,

The courses offered in Computer Science can be B.Sc. or B.Tech. For doing B.Tech you need to clear the entrance which can be at national level, state level or college level depending on the college you are interested in. If you are going for B.Sc. then you can get into with the help of Class 12 marks. But the cut-off will depend on college quality, seat matrix and category. With 86% you have chances to get into college. Still it will be good to check the previous year cut-off of the college you are interested in. As you have not stated the state to which you belong or the college you are interested in, I am sorry that I can give only general information.
