Hello,

I hope you are doing fine, If you had appeared for your practical exams and By some problem your practical marks didn't appear in the mark sheet then you should contact your school. You should inform your teachers as soon as possible. If you really appeared for your practical marks then they must be having the attendance sheet for exam. They will suggest you and do what should be done.

I hope you find this information helpful. I wish you all the best for your future.

Good Luck
