Don't worry it matters for a government seat, not for the private seats. Attend the counselling, during that you will get an offer from any private colleges for B.Pharm seat.

Hello Jayachandiran,
Your cut-off is very low to get a seat at any of the course at SSN College of Engineering. To get admission at SSN, you need to have at least 190 and above because the competition is too high. So, you cannot get a seat for IT or CSE at SSN.

With this rank, you can get a TFWS seat. Don't worry.
Good luck.

According to my knowledge, NIT-Puducherry is the best option among the two. They provide better facilities and good infrastructure and placement is also good at NIT-Puducherry.
Good luck.

No, there won't be any rewards for students, but upon your academical performance, you may get scholarships.
