Hello Rahul Sharma. Thanks for contacting Careers360 and we hope we will be able to answer your query.

Yes, you can appear for JEE Mains. JEE Mains can be given three times, in consecutive years.

So, you are eligible. Please prepare well this time as this is the last time you can write Mains.

I would advice you to thoroughly review all the concepts of NCERT / CBSE topics of class 11 and 12. Also, please practice the mock tests and the past year question papers by Arihant Publications.

Hope this helps you and all the best! 

Hello Rahul! I am sorry to say but no you can't appear for JEE Mains now as you need atleast 75% to appear for it if you are from general category. Hope this helps.
