Experience with McKinsey PST round?

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)

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 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,

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,

I suggest the following:

Do one full case from the 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 it quite fast. If lower - it will take couple of months

If your score is high:

• Buy Viktor Cheng test prep program - best materials I've seen so far. Works also for express prep.
• Practice 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)
• Do the 2nd test and check the score

If your score is low you need fundamental prep:

• GMAT IR, quant and verbal parts
• PST-like tests available online

Best,

Vlad

• Practice your math. Learn how to multiply double digit numbers (https://www.youtube.com/watch?v=6ndkkPZYJHo). Learn the division table up to 1/11 (i.e. 5/6 = 83.3). Learn how to work with zeros (E.g.: 4000000 = 4*10ˆ6)
• Do the 2nd test and check the score

If your score is low you need fundamental prep:

1. Understand where you have problems (Math, speed, critical reasoning)
2. Work on them:

• PST-like tests available online, GMAT IR part with the proper time tracking - for speed and math issues
• GMAT CR and IR parts - for critical reasoning issues
• Speed reading if English is not your native language and you need to improve the speed

Hi there,

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

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!

It actually very similar to the Practice Tests provided on their website. I found it qutie straight forward. Maybe experience bit of a time pressure. Overall, I did have a good experiece.

Hi,

I suggest the following:

1) Do 1 case from mck website in 60 min. Check your score. Target score is around 22-23 out of 26 correct. If you do 17-18 correct you have great chances to improve in a week or so

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)

BCG potential test is easier than PST, so if you score 18-19 on PST, BCG test will be not a problem

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

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

I found the Fless video sessions on Youtube very helpful

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

Hi Shree
