It’s probably apparent by the lack of replies that prep is probably not worth the effort. Not to say that you shouldn’t bring your best, but it’s a basic aptitude test and little more.
I paid heed to the briefing, namely to not bring a struggling performance in one section into subsequent sections; shake it off and refocus. Take breaks; I took about three strolls to the restroom and was one of the first to finish.
There were only one or two sections out of seven (?) that I didn’t fully complete. I used the scratch paper, but recognized two or three problems that were going to be especially long calculations to get the precise answer so I did a rough estimate and pressed on.
The monkey skills test was a little hokey, but I gave my best focused effort. The psych portion was maddeningly repetitive and banal, but maybe that’s the point...
Show up rested and relaxed.
