Honestly, probability questions are the easiest if you watch Chad's 20 minute probability video. The shortcut he uses is freakin' EPIC.
Just tried doing practice test #3 by timing myself and got destroyed lol. Only got 16 out of 40 correct. They seriously need to extend the time. I feel that you are NOT even allowed to think on this section. Either you know it or you don't.
You're right but if you practice, 45 minutes is definitely doable after doing a lot of problems. Even in word problems, you know what is expected and gonna know how to set it up right away.
I was thrown off a lot because I encountered so many word problems than I would've liked, but unless you run into these versions - 45 minutes should be sufficient. Just practice!
