Dear aspirant,

According to your question and taking into consideration that you want to get 10 CGPA and you want to know about the methods.

I would like to tell you that 10 CGPA is something that reputed colleges like nit iit some gfti's doesn't give 10 CGPA to their students but similarly it differs from college to college. Some colleges do give and they are giving now as the classes are online and all are scoring well.

For methods first of all you need to be very strategic and have to do a lot of smart work. You need to make a proper timetable of your subjects and follow that strictly.
