Hi,
I'm afraid the best and the only way is to download all casebooks available online and go through the math problems in the cases. Several formulas and tools can be useful:
- Interest rates calculations
- Compound margin
- NPV using the Rule of 72, Perperuity
- CAGR using the Rule of 72
- Currencies exchange calculations
- Speed, time, distance calculations
- Equations, systems of equations
- Ratio & Proportions
- Solving the problems by calculating the area of the triangle
- Profit / breakeven formula
- Correlations, outliers (being able to spot on the graphs, tables)
Best!
