Practising numerical questions is very important as numericals is a scoring section in JEE Main exam. This section does ot carry any negative marking. You must go through the past year papers in order to have a good idea about the type of questions asked. As Mathematics is a numerical based section, it requires thorough practise. You must also memorise all the **important formulas** well.

**FAQs**

Answer: NCERT should be treated as the base book for the preparation. However, it is not enough, thus you should also refer to other books like R.D Sharma, M.L. Khanna etc.

Answer: The first session of JEE Main 2021 will be conducted from 23rd February 2021- 26th February 2021.

Answer: The next session of JEE Main 2021 will be tentatively conducted in July or August 2021.

Answer: The revised dates for April and May sessions have not been released yet. However, the dates are expected to be out soon.

Answer: Mathematics section is considered to be tougher than the other sections. The difficulty level ranges from moderate to difficult.
