Hii Shubham
Your score is 52% so you will not be able to get NITs
So you can still pursue your B. Tech in private universities that also provide a good platform to get a top notch job
Some of colleges you can get admission are
LPU jalandhar
cu Chandigarh
LRIET solan
CGC Landra
and many more for more information about your engineering college you can check The following link

There are chances that you might get into a college but it depends on the stream you are from and there are colleges that take admission based on CET and not 12th standard percentage like if you have interest in law you can give BVP CET exam there is still time for that. For more details please mention your stream and your area of interest so that I can give you information in detail.

Dear student you get admission as per your choice but your percentage is low so you don't find very good college.
Thank you..
