Knowing math is really helpful, and here’s why: In the IBM exam, there are 9 topics to prepare for, but only 6 will actually appear in the exam. Out of those 6, we need to choose 2 to answer. So, when I did the math I realized that I know 5 of the topics. I figured I’d focus on those 5 cos’ even if 3 topics I studied don’t show up, at least 2 of them (hopefully!) will be in the exam. I’ll let you know the result after the exam to see if my math was correct 😁
