I took it years ago, indeed, and for what I am hearing from my coachees, has not really changed :)
It´s very similar to GMAT questions, not only in the focus -math, quick reasoning, etc.- but also in the format. It´s also very time stressful.
Practice leveraging GMAT materials -particularly the Quant section.
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/)
The key to success here is not only get practice, but learn techniques.
Hope it helps!
