Hi Bhavana,
As the cut off Thapar Institute of Technology is high compared to other private colleges so it might be difficult for you to get admission in the civil branch of the engineering in this institute.
Good luck.

You can get admission in any other branch, but in afraid you won't get CSE branch. Still go for counseling you may get lucky.

LNMIIT, Jaipur is better for CSE but you had scored pretty good marks you can try for some other good NITs like NITs in Jaipur, Allahabad, Jabalpur you may not get CSE here but for other branches also they are extremely good college.

Yes, in many field class 12th percentage matters.
But, in some fields there is no matter, but you should have more than 60% for safer side.
