Yes, you can but the counselling is over so the chance is only available through management quota.

Hello sachin!
Your rank is too low to get a seat at SRM University. If you have been called for counselling, then attend it. Maybe, you might get a seat with a high fee structure.
All the best!

No, I don't think so because counselling is over, but through management quota, you can get admission.

Hello Arnav,
I can understand your angst of preparing and appearing for different exams. It takes it's toll. Hence, MHA is pushing for single exam across India on lines of NEET. If it happens, it will be a red letter day.
Presently, you seem to have scored in similar pattern across exams. Just follow the link to know about probable college:

It is quite tough as your rank is less. It is not possible to get KTR campus, you must try for any other campus where you can surely get admission in civil engineering.
All the best.
