Hello student passing criteria isn't same for every board as it depends upon total marks, practical marks etc. But in general 33percent marks of your total marks is minimum marks Candidates need to obtain in practical as well as in main examination to obtain a passing certificate. Assume if the total marks is 100 and practical marks is 30 then you need to obtain 33 marks out of 100 and 9.9 marks out of 30 at least.

I request you to please help me with the board you're concerned about so that I can check and provide you with the exact information.

Feel free to comment if you've any doubt

Good luck
