Hello Aspirant,

One thing I need to clear that the board does not decide your marks, the marks are decide on the basis of how a student is. So it will all depend on your hard work. Nowadays there are many free online materials available for studying. Make a goal and set a target daily. Make notes and practice as much questions as possible as cracking 12th is not that tough task. Just need 1-2 month to complete dedication.

Hope this helps,

All the best and thank you!
