Hello
I am having issues structuring the math formulas (e.g. what to do given a both of numbers) and was wondering if anyone has recommendations for good case books to go through specifically for the math component?

Hi there,
Most casebooks have a section on math...but I wouldn't rely on this for your prep.
Some key formulas/concepts:

Hi there!
I would recommend you to use:
1) PrepLounge´s Mental Math Tool - https://www.preplounge.com/en/mental-math.php
2) Books for the GMAT preparation, especially pay attention to the Integrated Reasoning section
3) McKinsey PST
4) Take a session with a career coach to improve your math structuring and case solving overall
Hope it helps!
All the best,

Hi there,
I personally like INSEAD as casebook – including for math problems.
In terms of how to approach math in the case, this is what I would recommend:
In terms of general math tips and avoiding mistakes, I would recommend the following:
I would also recommend to practice math under pressure - not just math. Many candidates are totally fine doing 67% of 67 in normal conditions, but freeze if you ask this suddenly in a case interview.
In order to do so, try always to use a timer with a strict time constraint when you practice math – this will create pressure and help to replicate the actual conditions of the interview.
Hope this helps,
Francesco
Hey there,
80% of interviewees struggle with case math. Hence, it should always become a big focus of your interview preparation.
My approach to case math question would be the following:
I have written a very detailed and long (free) article on case math here and also developed a math video academy with 25 tutorials and a prep book with almost 2,000 practice exercises (which is key to train and prime your brain to come up with math questions):

In addition to Ian's suggestions, the McKinsey Problem Solving Test (https://www.mckinsey.com/careers/interviewing) is another great source to practice the underlying quantitive skills behind a case including structuring, exhibit reading, back-of-the-envelope math). It's no longer commonly used as part of the selection process but I still believe it's a terrific resource for practicing!
Hello!
To add on top of what has been shared before, I would practice with GMAT.
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!

All the GMAT prep materials work great. In addition, Rocketblocks is a great resource for all of these case interview skils you need to prepare for.
Hi,
In addition to the casebooks suggested, in interviews the aspect which causes more errors is pressure: start to solve calculations with strict time constraint. For longer formulas always share the calculation structure with interviewer before starting to write down the numbers: this helps to take time, to reduce the pressure and gives you the opportunity to receive a first feedback by the interviewer avoiding wrong calculations.
I recommend practicing with:
