Mult-pass system worked very well for me.I swear by the 3-pass system. I got all the low-hanging fruit, solved the ones I knew how to do, and then had an hour or more left to attempt the ones I knew would be hard. That way I didn't get hung up on anything and accidentally waste too much time.
I know some people worry about messing up the order of their answers on their scantron, but honestly, on a test this important, I would be double-checking which question I was answering no matter what.
