A student having no idea about the subject can’t face exams. People who are really concerned about their future take necessary steps for exams like, jotting down the notes when the teachers teach, trying to know about it more through different sources etc. and preparing notes based on that which is known as revision. When you revise yourself with more information, you’ll be able to face any kind of exam. The more you revise, the more confident you are. Exams give stress but when you know what and how to write, you gain more confidence.
5. Do we need revision for maths?
Yes. Practice is also considered revision. The more you practice the more you learn. Students might find formulas hard, but practising them every day makes it easy for students to grasp quickly. Maths is a completely different subject compared to any other subject. Once we start grasping, it becomes more fun to solve more equations. Some students find Mathematics as a very tough subject and there are students who consider it as their best one. It’s all about how you understand. Once you learn the equation, you will want to practice more.
