I'm also willing to pay as long as they really reflect what the test will be like
What is the most recommended source to prepare for BCG test?


First, do the sample ones on the website.
Once you complete them, let me know. I can share additional sources for free.

Hi,
There are 2 types of BCG tests:
- GMAT-like test with questions similar to GMAT
- Online Test that is based on a case and has the questions closer to PST
I have uploaded both test samples here (Online test is about airlines). I've also added BCG written case sample (Next round) and Bain written case. (Message me asking for a password):

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
Best!

Elisa - there is not much in terms of actual direct material, so many end up preparing the PST instead and hope it translates well.
Incidentally, for having worked with PrepLounge on their PST prep, I can assure you they are as truthful as any. [And I have no financial incentive to do so].

Hello!
I would practice leveraging GMAT.
GMAT unfortunately only gets better with practicing. Good news is that there are many ways of doing so!
There are free exams in the internet that you can use for practice (the one of LBS MBA page, Verits prep, as well as some free trials for courses such as the one of The Economist (https://gmat.economist.com/)
Hope it helps!
Cheers,
Clara

Dear Elisa!
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!
Best,
André

Hi Elisa,
BCG has been rolling out a new 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
- Calculators allowed
- 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.
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)
And much more ;)
You can download the guide instantly here:

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.
Best,
Francesco
