## **MCQs Questions for Class 8 Maths**

In this 21^{st} century,
Multiple Choice Questions (MCQs) play a vital to prepare for a competitive
examination. CBSE board has also brought a major change in its board exam
patterns. Now-a-days, a total of 10 MCQs questions are asked in the class 10
board examination.

In most of the competitive
examinations, only MCQ questions are asked. So, for getting ready for the
competitive examinations, we have to practice for MCQs questions to solve. It
strengthens the critical thinking and problem solving skills.

In future, if you want to prepare for
competitive examination and to crack it, then you should more focus on the MCQ
questions. Thus, from the board examinations point of view and competitive
examinations point of view, you should practice more on multiple choice questions.
