what marks should I get to get into nit Patna
Okay I'll mention the cutoffs of the previous years - The cutoff ranks . Because marks will change from year to year but what you can rely on is the ranks. So the computer science branch had cutoff around 11598 AIQ rank, civil engineering had cutoff of 16987 rank, Electrical engineering - 15493 rank, IT - 13477 rank, Mechanical - 14349, Communications Engineering - 15469 AIQ rank.
All the cutoffs that I've mentioned are of the previous year and for the general category. If you are from some reserved category then do mention in the comments so that I can provide you their cutoffs too.
