Caveat: I dont know the specifics

Having said that... I'd practice the McK PST test and others similar to it. At the end of the day, consulting is consulting, and we all look for the same qualities in applicants.

A bit of GMAT-type math wont hurt either obviously.

Good luck

Hello!

Although I don´t have the particulra experience with the test in China, the good news is that most of the online tests are very similar, and test the same skillset. It´s a good thing, since you can prep for them with a very unified approach.

I would strongly recomment you practice it with the Integrated Reasoning part of the GMAT exam.

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/)

Furthermore, you can leverage the MBB tests (https://www.myconsultingoffer.org/case-study-interview-prep/bcg-online/, https://www.psychometricinstitute.co.uk/Free-Aptitude-Tests.asp, and many others)

Hope it helps!
