you can go through the previous year papers to get enough marks ,because in CBSE exam many question are repeated  one.

for maths you can solve intext sums only.

for english you can read the chapters throughly and understand their meanings.

Hope this will help you

Hello Abhishek. Thank you for choosing Careers360.

If your target is just board exams for now, then you should keep your concentration to NCERT books only. Don't let your focus flutter. Try to cover up the syllabus from NCERT books and when you feel that it's done, you can start solving the previous year papers.

All the best
