And there is no national level entrance for M.Sc except IIT-Jam but it does not offer M.Sc in CS but if you want you can apply in DU and the admission criteria varies state and college wise like there is one state level entrance of Orrisa called Orissa University of Agriculture and Technology (OUAT) and at college level also there may be some entrances so it would be better if you could share which particular ones you are interested in.
