Hi Aspirant!

As we all know that the number of attempts for JEE Mains has been increased from 1 to 4 in a single year. And total you have 12 attempts (3 consecutive years) so you have plenty of time and chances for your preparation and eventually score good. See, if you think you are doing well in Jee Mains, moreover you are getting good marks in the jee test series conducted by your coaching centre and you are confident enough that you will be able to handle the pressur of jee advanced preparation then you must join it. But make sure you are not doing it in any forced condition and stay linient towards yourself. Also, make sure that this does not effect your jee mains preparation or marks.

Hope I anwered your query, thankyou!
