Greetings Ritu Pandey,

As I see your marks in JEE main are 66/360. If you are from a General category you won't be able to get into any national college. But you need not get dissappointed as you can get admission through many other colleges with JEE main score like

1) Dr B R Ambedkar National Institute of Technology Jalandhar

2) Graphic Era University, Dehradun

3) Indian Institute of Engineering Science and Technology Shibpur

4) Indian Institute of Information Technology Allahabad

5) Indian Institute of Information Technology Design and Manufacturing Jabalpur

Etc

Apart from these you can also apply for other private colleges who take admission through there individual examinations.

You can check on Career360 website for more colleges.I hope this information will be useful to you.

ALL THE BEST.

Regards,
