Once you've completed the test, be patient and don't worry too much about the results. If you have prepared yourself well, there is little chance that you will fail.

### Tip 1: Find out if the PST is part of your selection process

Usually McKinsey uses the PST forall entry level candidatesapplying for business analyst positions. However, if you come from one of the top MBA colleges and have been recruited on campus, you probably don't need to take the PST. Exceptions also often apply to applicants with work experience applying for associate positions, depending ongeography andbackground of the applicant. In particular, existing professional experience in another management consultancy plays a role.

There is no one-size-fits-all rule as it depends on the individual candidate. Therefore, you should do this directly with yourClarify local HR contact. There are no disadvantages for you if you ask in a friendly email whether the PST is part of your application process.

### Tip 2: You should master data analysis in your sleep

Tables and charts are usually part of the PST. Therefore it is importantInterpret data quickly to be able to. If you are quick to read diagrams and theirKey message understand, you will also save valuable time. When analyzing data, you should consider the followingFollow 2 steps:

1. Find out what the table or graph represents! You can often tell by simply reading the heading and the labeling of each column and row.
2. Read and understand the data! You may have to do some math here - in your head or on paper. Ask yourself the question: Why was this data presented to you? And don't get distracted by data that needs more information and that cannot be exploited without additional assumptions.

By the way: Even if the PST is not primarily designed to test your business knowledge, you should be familiar with all common business terms.

### Tip 3: Choose your preparation material carefully

There is a wide variety of PST practice materials that you can find online. Caution is advised here, however, as the quality of the practice tests available varies greatly. There are a number of dubious providers whose exercise material often has a significantly lower level of difficulty than the real McKinsey PSTs. Here you should include factors such as the size of the offering website and, above all, transparency, i.e. who is behind the page and the PSTs, in your decision.

In order not to waste time on inadequate materials, it is crucial that you have thebest source for your preparation find. First, you should understand the PST from the ground up. Our McKinsey PST Guide explains the general test structure and gives you useful tips so that you are prepared for any type of question.

### Tip 4: Practice the PSTs under real exam conditions

As you practice the PSTs, keep the following points in mind:

• Don't use a calculator! Pocket calculators are not allowed, so get used to mental arithmetic as you prepare.
• Do not use any additional paper! Sheets for notes or ancillary calculations are not allowed during the PST. Therefore, you have to be able to do all the necessary calculations in the limited space of the PST booklet. By including this condition in your exercise, you will be used to it on the day of the exam.
• Stop the time at 60 minutes! Try not to linger on a question for more than 2 minutes - this way you will be able to get it ready in time. If you find it very difficult, you can go through your first test without a stopwatch to get used to the style of the questions. For additional practice tests, however, you should limit the time to 60 minutes.

Check your result after each practice test, find out what kind of questions are causing you problems and focus on them by doing additional exercises with this topic focus. However, if there are areas where you are simply weaker, don't stress yourself too much. Over time you will get to know different question and answer types and find your own flow so that you can quickly recognize which questions you need to estimate, skip or answer immediately.

### Tip 5: become a mental arithmetic pro

In general, the difficulty level of each PST question is not particularly high. What makes the PST so difficult is the limited time you have. So start practicing your mental arithmetic skills - this is the most obvious tip to follow when it comes to saving time. This will also help you avoid using a calculator or extra paper for ancillary bills. The trick here is the right type of preparation:

• Learn the right tools: you shouldMath basics and know abbreviations like the rule of 72. You should be able to do simple multiplications, written division, fractions and percentages while you sleep. With our mental arithmetic tool you can train these skills in a targeted manner.
• Use these tools properly: Practicecorrect arithmetic first. It doesn't make sense if you do the math quickly but get wrong results.
• Use the tools - and do itfast: When you are sure that you almost always get the right result, you can start training your mental arithmetic. The rule here is very clear: Practice makes perfect!

### Tip 6: Learn how to read faster

PST questions contain a lot of information and data, not all of which are relevant to answering the questions. As soon as you feel confident doing mental arithmetic, you should improve your reading speed so that you can learn to deal with the amount of information under time pressure. There are a few points to keep in mind:

• Practice quick reading! There are several online“Speed ​​Reading” exercises and even smartphone apps that can double the number of words you can read per minute. After just 15 minutes of practice, your reading speed will improve.
• Always read the question first! To help your brain focus on relevant information, you shouldread the question first, then the answers and finally the additional information. In this way you train your brain to look at the information you need and to skim over useless spots.
• Learn theimportant information easy to recognize! After you have completed various exercise PSTs, you will be able to recognize patterns and decide which information you should read and which information you do not have to pay attention to. With enough practice you will get a feel for the wording of the questions and you will know exactly where to find certain information. The answer to a question can often be found in just one paragraph or diagram.

### Tip 7: answer EVERY question

The PST is a battle against time, but one positive attribute of the test is that it isno negative distribution of points gives. This means that there is no punishment or minus points for wrong answers. That's why you should answer every single question - even if you're just guessing. In order to increase the likelihood of a correct answer, you should eliminate the answers that definitely cannot be correct. The elimination process generally helps you to come to the solution that is most likely correct faster. Especially when it comes to numbers, by only roughly estimating the calculation, you caneliminate wrong answersthat are far from the answer or that contain incorrect decimal places.

### Tip 8: Be disciplined and don't waste too much time on a question

A rule of thumb is that if you have, you should move on to the next questionwithin the first 30 seconds don't know how to solve the question. That doesn't mean you have to solve the problem in 30 seconds, but you should already know after 30 secondshow you solve them. Even if you know how to solve the question, do not spend more than 2 minutes on a question. With practice, you will be able to identify difficult types of questions. If you come across a question that turns out to be very difficult,resist the temptation to loosen it, even if you have already invested a few seconds in the question. Trust your gut feeling, guess the answer and move on to questions that you can solve right away. It is important to be disciplined! Imagine someone looking over your shoulder and giving you objective advice on when to skip a question. If you are not disciplined here, you will waste too much time on some questions. If you still have time at the end, you can always go back to the question and try to solve it.

Since you are not allowed to use additional paper for notes or ancillary calculations, you should get the most out of the paper provided.Marking important numbers and keywords helps you to quickly recognize the answers in the text. Your time is too valuable to be able to do quick and accurate calculations on the numbers in the wrong row in the table.

The same applies to possible answers that you have eliminated:cross them out! So you don't have to think again if you reread the question. Make sure you didn't forget to mark the answer to a question that you solved. It would be a shame if you lose points because of such inattentiveness.

### Tip 10: dress appropriately

Usually the PST in the McKinsey office takes place on a different day than the actual case interview. So there is basically no way to impress anyone or to network with McKinsey consultants. Nevertheless, you should dress appropriately, which means in consulting:put on a suit. We know that many candidates make this mistake and leave a bad first impression with it!
