JEE Main

No I didn't think so.

Hello Muhammad,
The age limit to appear for JEE Mains is as follows-
Candidates should have been born on or after October 1, 1993, shall be eligible for JEE Main 2018. For SC, ST, PWD candidates, the age relaxation of 5 years is applicable. Hope this will be helpful for you.
Thank you!

You can use Shiksha's college predictor tool:

For NITs, you have to clear JEE main exam.

No, it's as same as JEE but TNEA is conducted by state and JEE is conducted by central and both a entrance exam.

You can use Shiksha's rank predictor.

There are less chance to get top NITs for CSE branch with 180 marks if you are from general category. If you are from SC, ST category then it may be possible to get a good NIT. In general category, you should get 220 and above marks in JEE Mains. Good luck!

Hello Reetika, It is difficult to get a good college under JEE counseling with this score. So you may try for colleges with your board exam marks or via any other entrance exams. All the best!
