It's really more of a speed/pressure test than content. It's full of mental math and tricky wording to slow you down.

I've taken the real deal (albeit as a freshman in highschool, dad had to take it for work) and got something like a 29 but the test gets significantly harder as you progress.

It's different than the online tests where the difficulty is flat, that's why you rarely see scores above 35. I got through 44 questions and got an 86% without paper (I'm in school for consulting so I do that kind of math a lot) and I remember the real test being an absolute animal.
