I would like to appear for GSEB HSC practical exam in march 2020 and remaining subjects in July 2020. Can I get only one mark sheet for both exam?
Your part is to appear the exam. How you will receive mark sheet and in what number depends on board. They are the sole person who decide how to make mark sheet which will be easy use for students.
so don't worry about that part. Read , practice regularly so that you perform well this time.
Hope it helps!
