Hello aspirant

Now that you have registered yourself to appear for all the subjects , which means you are repeating 12th standard again. The board views you as a normal 12th grade student.

Hence, you have to appear for all the exams (internals and externals), practicals, assignments etc.

Hence, the answer is YES.
