I have an invitation for the 45 min 23 qn online test soon (not the GMAT like qn. but more like a case with many questions).
But resources for preparation is very limited. I have downloaded the free sample on Igotanoffer.com to get an idea. But their full package is very expensive and not sure if it is a good investment (after all not a lot of questions in it either...)
Does anyone have suggestions for how to prepare for it other than buying the expensive prep package? Thank you very much!
If possible, don’t print the sample tests; rather, do the simulations on your computer. The day of the test you won’t be able write notes near the questions or turn pages. If you practice on a paper version, you will find different dynamics the day of the interview that could impact your performance. You should also do all the simulations with atime constraint
After each test write down the mistakes you did. You will probably find that the mistakes have something in common – eg wrong math, too much time wasted on some questions, wrong interpretation of graph
Work on each area of improvement. Many candidates do these simulations checking only the final score and don’t spend time analyzing the mistakes - thus they don’t improve
Once you have done all the BCG test simulations, move to PST practice. You can find a good number of PST tests online. The PST is different from the Potential Test – in the PST there are multiple cases, the types of questions are different and you have more time available. However, it may still help to improve your performance
As additional notes:
Remember you are penalized for wrong answers - you should adapt your strategy accordingly
Aim to identify the main areas of improvements already with the first test - the typical ones are math, graph interpretation and ability to absorb information quickly
Try to distribute the tests between the day you start practicing and the day of the test for constant learning – avoid to do them just at the end
If you want to practice on a real example of a BCG Potential Test, you can find the one I prepared below:
Prepare on the exact same format of the BCG Online Case – 23 questions in 45 minutes
Identify your possible improvements thanks to detailed solutions for all the 23 questions
Practice on material tested by multiple candidateswho did the test and successfully passed the Potential Test.
Below you can find a screenshot of the test:
That being said, BCG has been rolling out a new BCG Online Case (also called the Chatbot Interview) since 2019. It is a 8-10 questions test structured in 2 parts:
8-10 questions to be taken in 25-30 minutes
1 video interview question at the end, where you have to provide a recommendation
The main differences compared to the previous version (BCG Potential Test) are the following:
8-10 questions instead of 23
25-30 min instead of 45
Presence of open questions
Video sum up at the end
The main challenges based on the candidates I helped are the following:
Time. Questions are not particularly difficult, however you will feel time constraints also due to the fact you don’t know how difficult the next questions could be - thus how much time they may require
Chatbot interaction. Unlike a test like the McK PST, you cannot proceed “at your own pace”. You will have to follow the evolution of the test as questions are revealed one by one
Math. Candidates often find the math quite challenging given the time constraint
If you want to prepare in the best possible way, I created a guide exactly for that as well.
This guide will:
Show you the perfect strategy to answer the 5 types of questions in the Chatbot
Offer you a clear strategy to optimally structure the One-Way Video Assessment
Provide insider information from previous applicants who succeeded the Online Case
Structure a clear preparation plan based on 6 FREE PSTs and Potential Tests
Replicate the same experience of the interview thanks to 2 FREE Complete Chatbot Cases (Casey-style)
As an extra bonus, I am currently offering the BCG Potential Test #1 (worth $39) and Graph Analysis Cheat Sheet (worth $29) for free with the guide. That may change in the future so hurry up if you are interested ;)
If you need additional support or have any questions on the guide please feel free to PM me, I will reply within 12 hours.
As for particular recommendations for online test:
Try to find as many people in your country as you can who have done the test. Ask them for the topic, industry, and questions they remember. For example in one of the countries there was a test about airlines and reading a couple of articles / company reports / wikipedia articles with industry terms could significantly improve performance
Try to practice tests with strict time-management. McKinsey PST from the official web site and all mck and bcg -like tests you can find online
Additional resources can be GMAT Integrated reasoning from the official guides and apps if you feel that you are not p[erforming well
As far as I remember calculator is allowed on BCG test. Make sure you know how to simplify calculations and use it fast

If you have already started your preparation for case interviews and good at reading charts, analytical thinking, and mental math, then BCG potential is an additional of probably an hour as what you should plan for.
Basically, to prepare you can use some mock potential test, and after every test just look into solution to see where you have gone wrong. 3-4 mock test it would be enough for you to prepare for the potential test.
If you need any further help, feel free to reach out.
BCG test includes 23 questions and you will be given about 45 minutes to complete it. This means you will have two minutes to solve each question on average.
The BCG online case is very similar to a regular case the only difference being that your direction in the business case is guided by the questions being asked. So it will be similar to an "interviewer-led" case format. There are a lot of resources online for case solving and all you need to do is Google. If you want to sharpen your case skills in general I would recommend Victor Cheng's Case Interview Secrets by Victor Cheng and his book.
However, since the BCG Online Case is also a single-choice test, you can also use this format to your advantage. You’ll receive+3 points for correct answers and -1 for wrong answers. Currently, the inofficial cut-off score is below 70-75%.
Message me if you have any other specific questions and all the best!
