Hello!
I wuold suggest you to practice with GMAT.
GMAT unfortunately only gets better with practicing. Good news is that there are many ways of doing so!
There are free exams in the internet that you can use for practice (the one of LBS MBA page, Verits prep, as well as some free trials for courses such as the one of The Economist (https://gmat.economist.com/)
Hope it helps!
Cheers,
Clara

Hi Alex,
the most common formulas you need to know in a consulting interview are:
- Breakeven point
- Rule of 72
- Perpetuity formula and general NPV formula
Besides that, you should be familiar with simple and compound interests.
Finally, you may want to review the formulas for volume/surface of the main solid figures (pyramid, cone, cylinder, sphere), which could be useful in market sizing cases.
Best,
Francesco

Hi Alex,
I see two aspects to your question:
- Case interview math: Just google this term "case interview math" and you will get more than enough resources
- More general case interview frameworks and business concepts: I wrote a book very specifically for this topic giving a) an overview of relevant business concepts and frameworks and b) how to specifically use this concepts and frameworks in a real-life approach: http://cif.consulting-case-interviews.com/
Hope that helps!
