Dear aspirant,
As you want admission in nit Raipur cse and considering you would be having the benefit of home state quota and obc then you need to score atleast 180+ to get into this branch in this college.
As you are now starting from zero let me tell you that it's very important to be focused and study very efficiently. It is not required to study 10-12 hours in a day. But whatever you have studied you should have studied very efficiently because you should remember whatever you study and kindly practice as much mock papers you can.
