The case study questions in class 12 Mathematics bears 8 marks. As all of these are only MCQs, it is easy to score good marks with a little practice. ## Case Study Questions in Maths

Let’s have a look over the class 12 Mathematics sample question paper issued by CBSE, New Delhi. Question numbers 17 and 18 are case study questions. If you go through each MCQ there, you will find that the theme/case-study is common but the questions are based on different concepts related to the theme. It means, if you have done ample practice on the various concepts, you can solve all these MCQs in minutes.

The difficulty level of the questions is average or say easy in some cases. On the other hand, you get four options to choose from. So, you get two levels of support to get full marks with very little effort.

## But Don’t Forget to Practice

Most of the time we feel that it’s easy and neglect it. But at the end, we have to pay for this negligence. This may happen here too. Although it’s easy to score good marks in the case study questions but if you don’t practice such questions, you may lose your marks. So, we suggest students should practice at least 30-40 such questions before writing the board exam.
