McKinsey Problem Solving Test

Hi Paola,

in addition to what mentioned by Carlos, I would recommend you the following:

• Commit to a time for each question, and go on if you surpass that time. If you do not set discipline, you will end eating too much time for some questions (these tests sometimes are actually structured to have some questions it is better to skip and review at the end). If time and test allows, you can then go back to the questions at the end.
• Practice a lot of math before (GMAT or online resources from Victor Cheng and/or PrepLounge)
• Use elimination process when in doubts
• Practice graph interpretation
• Practice quick reading and quick understanding of key information only
• Remember there are no penalties in the test, so you should try to answer all the questions

The best practice you can have is doing the higher number of tests you can find online; besides the 3 on McKinsey website, you should find additional 3-5 that you can buy online (or simply ask an expert if they can provide them and book a session – many of us have samples available. In this way you would get both the tests and a session).

You can also find some additional tips from Vlad at the following link:

Hi Paola,

First of all, congrats on the invitation and best of luck in the process. A few of my friends have had experience with the PST and I'd be happy to share a brief overview of their suggestions / best practices.

In short, since the PST tests business acumen along with math abilities, it is important to practice both of these areas. The main difficulty with these tests happens to be the fact that you will not have enough time to comfortably answer each question. Therefore, it is important to be agile and precise.

In terms of tips and tricks, I would suggest the following websites (see below) to go through some sample questions. At the same time, it is always great to work on your mental math (PrepLounge offers some good resources for this). *Note: I've included GMAT and GRE questions because these are challenging and, in some ways, reflect the mental process you'll need to solve the PST math problems.*
