I am just starting to study how to do cases, and I didn't use math in like 6 years, my studies didn't require any math besides introductory microeconomics, macroeconomics, and statistics courses. I need to learn math super fast, and I see how it also affects me with charts.

I CAN understand numbers, and how to use them when I have a guide of the rules and exercises to practice.

I just don't know when to find them, and I would love it if you can advise me on the math and charts, and the quantitative aspects of the cases.

1. where can I find math practice and chart practice?

2. Any tips on how to do it effectively and faster?
