M and N are good blocks. Try to take 3 or 2 bed rooms don’t go for 6 beded. Prefer M block over N
Try to make as many friends as possible in first semester only cause after first semester you will be having ffcs and all that shit so it would be difficult to make friends. Be active and make friends in first semester along with this do focus on your academics that matters a lot in VIT.
Advice : try to Be among top students in your branch in first year and then after first year change your branch.
All the best 👌🏻
