Any body tell me plzzzz .....i hav recently started to do question paper so how many should i do???
Dear Shaina,
There is no such limitation on solving previous year papers or mock test series you should solve as many as sample papers for your practice.
To score good marks make sure you should have good hold on PCB subjects. Refer NCERT books to work on your concepts and to build your fundamentals strong.
Good luck!!
