## Important Topics from NCERT Textbooks for CBSE Class 12 board 2018 exams

#### Important Topics from NCERT Textbooks for CBSE Class 12 board 2018 exams

Here we are discussing a few topics which are important from the exam point of view for 2018 Math board exam of CBSE class 12.

Here we are providing important topics from each chapter for CBSE class XII Math board exam 2018. Most of these topics are taken from NCERT Textbooks (Part I & Part II). CBSE 2018 datesheet is already announced. We now know that board exams for XII shall begin from 5 March and, 21 March is the day for Math Exam.

This subject Math requires lots of practice but now very less days are left. So, now students need to focus on practice and revision, rather than studying any new topic(s).

Students preparing for CBSE Class XII Math exam are suggested to go through latest Math Sample Paper issued by the Board. You can watch this Sample Paper at our YouTube Channel too. This sample paper is recently released by the CBSE (in October, 2017). Doing latest sample paper issued by CBSE always helps in understanding pattren of the paper.
