I need to improve the quant part of my case cracking. Suggestions on the casebooks I could use or other tips? Thanks! :)

Hi,

Here is how you can improve your math skills:

1) Fast math - train, train, and train again

• Learn how to multiply double digit numbers (https://www.youtube.com/watch?v=6ndkkPZYJHo)
• Learn the division table up to 1/11 (i.e. 5/6 = 83.3)
• Learn how to work with zeros (Hint: 4000000 = 4*10ˆ6)
• Use math tools (Mimir math for iOS), Math tool on Preplounge website to practice

2) Quant part of the case

• Simply download all casebooks available online and go through all cases. Pls disregard the structuring part and just practice the quant part. The number of distinct math tasks types is not infinite and you can train all of them

3) Critical Reasoning (for PST)

• GMAT test CR and IR parts (Official guide and Manhattan prep)
• Mckinsey practice tests
• PST like tests from the web

4) Working with tables and graphs and deriving conclusions

• Study "Say it with Charts" book
• Check all available MBB presentations and publications. Practice to derive conclusions and check yourself with the actual ones from the article/presentation
• GMAT IR part (Official guide and Manhattan prep)
• Learn basic statistics (Any GMAT or MBA prep guides)

5) Case math

Practice common market sizing topics (Airport passenger flow, real estate volumes, subway passenger flows, car usage, etc.). You should become comfortable with making assumptions

Learn key financial topics (P&L and balance sheet and how to analyze them, Basic Valuation principles via NPV and comps) and case math:

• Interest rates calculations
• Compound margin
• NPV using the Rule of 72, Perpetuity
• 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)

Good luck with your interviews!
