Hello,

How your OBC rank is high and General rank is low. There might be some mistake while writing the question.  Anyway your categorical rank is low and you can get any top college. You can get CS branch for sure even with 3650.

You can also apply for IET which one of the top and best college. You can apply for TFW for which you don't have to pay Tution for every semester.

Hope it helps!
