Yes gajanan.

An aspirant can appear for jee maina for maximum of three times in his/ her life. So you can appear for jee mains  the next year if its not your third attempt . All the best for your exam. Feel free to ask more queries!

Hello gajanan

You can give jee mains and jee advance again with better preparation and better confidence again.

As you already cracked jee mains,it means you have a good understanding in basic concepts and you just need more practice and need to study some JEE advance topics thoroughly again

Best of luck!
