Hi, I've taken it a couple of times during my initial cadet selection phase.
The math there is pretty straight forward, almost everything is as you have mentioned above. Nevertheless it does have some percentage, equation and a little bit of the basic algebra. Equations are linear, so they mostly will look like 2x+3/4=5. Algebravise you are going to have something like (2a+3b)/4c where are a=1 b=4 c=7. As you can see it's a pretty basic stuff. The thing is you will have about 25 tasks to solve for a limited amount of time. So I would strongly suggest to focus on your ability to do all these things as quickly as possible.
P.S. You can google latestpilotjob website, it has some useful stuff for preparation.
P.P.S. You can PM me if you still have some questions.
