Hi,

There are 2 types of BCG tests:

1. GMAT-like test with questions similar to GMAT
2. 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:

(ask me for a password)

As for particular recommendations for online test:

1. 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
2. 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
3. Additional resources can be GMAT Integrated reasoning from the official guides and apps if you feel that you are not p[erforming well
4. As far as I remember calculator is allowed on BCG test. Make sure you know how to simplify calculations and use it fast

Best!
