hello pranjal,

same problem m also facing. few months earlier before exam i went to the cbse regional office noida. Staff there told me that we all private candidate will get marks on the basis of our theory performance. 20% marks will be given of theory. means if u get 45 in maths theory then u will get 9 marks in ur practical jzt because 20 percent of 45 is 9. hope u understand what i explained with lots of grammatical error. lol

It would be really helpful if you can state your question properly so that we can understand and help you out.

But to mention, with every change in the syllabus for this current year 2020, all the exam pattern and marking scheme for each subject will also we notified with time.

Keep a check on release of any official notices or announcements. I hope this helps you!
