Hi Raj Kumar, hope you are doing well, yes you can go for jee mains again if you feel you haven't scored good in your first attempt. After completion of your board exams you can even study for one more year and get admission into good college. The only problem is you will lose one year if you are thinking of preparing for jee mains again after completion of your board exams.

I think it helps you!!!

Keep Smiling:)

Wish you good luck:)
