Hi together,
I am ok in most parts of the cases. However in the math part, I always get the problem wrong or generally dont understand the math problem. Where can I practice those or do you have any tips how I should prepare them?
Thank you!

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

Hi Alina,
Have you practiced the math part for actual cases? If not, doing the math part only using some good casebooks (eg INSEAD) would be a good starting point.
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):

Hello Alina,
There are two big workstreams when it comes to the math part of a case:
Hope it helps!

Hi Alina,
Here is a math app for practicing math fractions and percentages from one of PL participant https://apps.apple.com/us/app/case-math/id1507653375?mt=8&ign-mpt=uo%3D4
Here is a tool provided by PrepLounge https://www.preplounge.com/en/mental-math.php
For practicing and improving your math you can find also some apps and tools, besides Victor Cheng’s math tool (Magoosh's mental maths app, Mental math cards challenge app, etc). But there are some facts that will help in overall improvements:
Hope it helps!
Cheers,
GB
If you want to practice the execution specifically, there are tools here on preplounge and other platforms like Rocketblocks.
Hi Alina,
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:
