Hello PL community! Reaching out to ask for advice and experience/s with Mckinsey's PST? I have asked several peers about their experiences and how good/bad they felt after taking it and have received varied feedback!

Looking to hear about experiences, and what was the best way you prepared for it!

### I have my McKinsey PST in another 3 days. I have a basic idea of the Test. Please anyone help me how to crack it with only 3 days preparation

Hi,

I suggest the following:

1) Do 1 case from mck website in 60 min. Check your score. Target score is 22 out of 26 correct. If you do 17-18 correct you have great chances to improve in 3 days. If lower - reschedule the test.

2) Buy Viktor Cheng test prep program - best materials I've seen so far. Works also for express prep.

3) Do the 2nd test and check the score

4) Use other materials: GMAT IR and verbal parts, PST-like tests available online. The key thing - you should train to do them, fast

5) Do the 3rd test and check the results

P.s. in parallel train your math. Check exercises on Cheng website. Key things - multiplication of 2 digit numbers, operations with zeros and division (Learn division table, ie. 1/8 = 12.5%, 8/9 = 88%, Learn up to 8/9)

Best,

Thank you very much Vlad :) I'll do as you said. Hope I'll crack it...cheers..!!!

### Action Plan to prepare for the McKinsey PST

Hi,

I just took and passed the PST test.

I noticed the following things:

• I did a lot of preparation. I worked through the McK practice tests a couple of times. I did some of the external tests provided by a few websites (they were on a different level most of the times - best preparation was the McK tests). Total maybe took 10 practice tests (2 times the 3 original ones, and whatever I could find).
• Once you know the type of quetions they are asking, it is pretty straightforward.
• I found a lot of people that showed up on the day were less prepared: They had only done 1 test, heard about the test a week before, thought it would be a 'either you have it or not' situation.

Therefore, my personal view is that the PST is a really good way for McKinsey to weed out applications that just apply for fun and games, and don't really want to put effort in. Those people may be capable to do the job, but doing the test without preparation is hard (I had to let go of some GMAT logic as I was just answering a wrong question...).

If you prepare with the materials available and speed up your maths, you should be good.

Hi

Firstly, please learn to use the search bar! A valuable skill for consulting if you can land a job.

Secondly, I was in your position 2 months ago.

In 1 month, i went from getting 30% on untimed tests, to passing the PST!

This is what i did:

• Igotanoffer practice tests
• Mconsulting practice tests
• Official McKinsey tests
• Practice speed maths - learn shortcuts like rule of 72, become a gun at the times tables, long division, estimation, growth rates, change %
• Use youtube- Cant remember who exactly but there is this Russian guy who has great tips and logic around the PST.
• I learnt to speed read - i went from 350 words per minute to 650. Youll also learn what info to read and what not to bother with by doing enough tests.
• I went through McKinsey presentations and learnt about the type of charts often used, learn how to read them quickly as this will save you minutes in the test working out what the hell they are even representing!

You will identify trends with answers, question types and the flow with time. Its frustrating and hard work, but worth it to pass! Youll also learn about time traps and which questions to estimate, leave and compute.

Start off doing the tests untimed, and re do tests over and over again.

Then slowly introduce time constraints and work to doing them in just 1 hour.

All the best.

Cheers,

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).

Best,

Francesco

Hi Francesco! Thank you for your suggestions, I really appreciate it.

Hi there,

Careful since McKinsey has rolled out Imbellus game in a lot of geographies.

Best,

### McKinsey Problem Solving Test

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.*

Mucho éxito!

Gracias Carlos! I've been practicing my mental math skills and I've reviewed McKinsey's online sample tests. I would take a look at the other resources you've recommended. Thank you again!

### McKinsey PST

Hi,

for many people using the GMAT test books was helpful.

I would reccomend you use Manhattan GMAT books about the quantitative part of the test - in terms of general preparation

Another suggestion that I would give you is to really make the best out of the tests you do by

1) Re-analyzing them in deep, understanding the errors, categorizing the possible questions type and patterns - trust me it seems obvious but it is a huge effort to go back and look carefully - you can gain a lot from that if you really become "structured" about it

2) Maybe you already have explored - but just googling you find many resources that teach you basic strategies for the different type of questions of PST

Hope this helps.

Regards,

Paolo

I also practiced a lot with GMAT preparation books, and it worked!

### I have my McKinsey PST in another 3 days. I have a basic idea of the Test. Please anyone help me how to crack it with only 3 days preparation

Hi

3 things in this order

- do all the tests in McK web page

- do tests in BCG web page (it is somehow similar)

- practice GMAT exercises - math part obviously:)

with this is more than enough!

cheers

Carlos

Thank You very much Carlos.. I'll prepare my best from these sites and solve as many tests as possible..
