Seriously, I don't remember seeing much of that on the entrance exam and I know for a fact I haven't seen any of that since then.
I have just now started my third year of apprenticeship with the Local here in Atlanta. I will advise you to keep your math skills before you fill your head up with that junk.
Basically all they want to know is this. Can you see two dimension and make it happen in a three dimensional work place?
That comes into play with reading prints and that is a major part of the job in latter parts of your training. But don't stress on it for now.
Just my opinion though. Take it for what it's worth.
