It seems like you need to discipline your approach.

Try solving all your math problems only in algebraic form - without any numbers. This way - you will be able to create a rigor in your mind.

Other than that - always work from the top.

• Write down the equation of your final objective first. Even if it contains 2 values that you will calculate in the rest of the case.
• Then keep breaking down those values step-by-step till you have the full formula opened apart.
• Then see what all quantities need mathematical calculations and simply execute.

Happy to guide you in bullet-proof quant through a coaching session.

Hi there,

This is indeed an interesting question which is probably relevant for quite a lot of users, so I am happy to provide my perspective on it:

• First of all, I would advise you to become familiar and have a look at model solutions of often found concepts such as break-even point, NPV, ROI, inventory turnover aso.
• Moreover, I would advise you to practice quantitative questions either from case books (for instance, CaseCoach offers mostly interviewer-led case studies where you can quite easily just practice the quantiative questions) or from text assignments from high school.

In case you want a more detailed discussion on how to best practice structuring quantitative questions, please feel free to contact me directly.

I hope this helps,

The general “rule” is that you should structure first, and only later do the math. You should avoid doing both at the same time, because it leads to the problem you mentioned.

Regarding how to creat a good structure, have you read Preplounge's bootcamp article on market sizing? It's a good foundation for that:

If you still find it hard after going through this article reach out and we can discuss further.

Hi!

It's crucial that you structure the problem analytically by, for example, creating an issue tree via the algebraic formula you want to develop and compute.

Market sizings are particularly useful to learn structuring and analytical thinking.

Let me know if I can help you with your preparation with structuring math. I have specific sessions tailored around this important part of the case interview.

Best,

Anto
