**How to prepare and score Good marks in Math Paper?**

As far as competitive exams are concerned, especially those related to the engineering field, Mathematics becomes a very important subject. It is easy to score a 100 in Mathematics in board examination. You just need to work hard with dedication.

- Prepare a good Timetable – Have an ample amount of sleep and small breaks in between your study time. A minimum of 4 hours a day is necessary to score well in Maths. Sleep and proper diet will help you increase your concentration power. Also, try to make your timetable in a way that is able to complete the harder and boring chapters first. So that you remain free from any kind of stress and can prepare well for board exams.
- Keep a reference material at hand (CBSE Study Material/CBSE Study Notes) – The best reference material is the one that has maximum accuracy and least scope for errors. These CBSE Study Material/CBSE Study Notes are just the right thing to keep as a reference. You can also find Toppers’ notes online, for free. Just like the CBSE materials, Topper’s notes are also a very good source of accurate and up-to-date information.
- Solve the CBSE previous years’ question paper – The most reliable way to test your preparation is to solve the CBSE previous years’ question paper. This will help you identify the chapters where you need to give extra attention to. This way you’ll be able to prepare good answers for boards.
- Try online test of maths class 12 – After solving the previous years’ papers, you can solve these class 12th practice tests. These online tests of maths class 12 will help in enhancing your skills by the variety of questions they offer. The pattern of questions asked in these class 12th practice tests will prove to be useful in strengthening your concepts and analytical thinking.
