Hi,

As for your 1st question - the best way is to **download all available case books and go just through the math problem. **There is a limited number of types of problems in cases and you can cover almost all of them

Basically, you need to **develop 3 calculation skills: **

1) Learn how to **multiply double digit numbers **(https://www.youtube.com/watch?v=6ndkkPZYJHo).

2) Learn how to** work with zeros**. Best way - always use 10^power instead of zeros

Example:

300x9000 = 3*10ˆ2 x 9*10ˆ3=3x9*10ˆ(2+3)=27*10ˆ5

Handwritten it looks not that complicated. If you get used to writing all the numbers that way, you will never lose zeros and all multiplications/divisions will be replaced with + or -.

3) **Learn the division table** up to 1/11 (i.e. 5/6 = 83.3%). It will help you calculate any percentage problems

Use math tools to train (Preplounge tool, Mimir math for iOS, Math tool on Viktor Cheng website). Train, train, and train again

Good luck!
