Hello Grace

I am here to help you with your query.

According to the norms ,jee mains has got 3 attempts and Jee advance has got 2 attempts to be tried by a candidate.

As you are concerned about only JEE adv then ,you should write immediately the next year .

Yes you can again go through the same mains and then advance .

You have a chance for further attempt .

Look at this link for clear information .
