Hi,

Yes , you should definitely revise from NCERT before your board exams because the paper would be set according to NCERT syllabus itself. I would urge you to revise it atleast once.

All the best!

Hello,

.

Never underestimate NCERT books more importantly if you belong to CBSE board. These syllabus books hold true significance to the board exams and are best to practise. No question comes out of the syllabus and so always stick to the syllabus and if it is NCERT, it is more better. Studying NCERT books and then trying to answer the questions given in chapter wise papers will also help you. So if you have only 30 days time and you haven't started your preparation yet, then NCERT books will help you. If you have Chemistry as one of the subjects, then the question paper is completely based on the content from NCERT books. Go through everything from NCERT and practise as much as you can. Do not leave anything for the last minute because then even NCERT will not be enough for you to score good marks.
