Hello student to be honest yes 42 percent marks is little less but it's not like you can't make your future, I request you to please help me with the preferable course you're willing to pursue after class 12 so that I can offer you the best eligible options for you

In case if you're not satisfied with this marks you can appear in improvement examination and increase your marks.

Be positive and think positive marks is important but not everything to decide about your future.

Feel free to comment if you've any doubt

Good luck
