I was wondering: What book has the best alternative practice tests, specifically for the math and science sections? I'm talking about books such as Barron's 6 tests, Kaplan, Princeton review etc. Which should I use to improve my score fastest?
I don't want to waste the Real ACT practice tests, but still need to practice for math and science. Anyone advice from someone who has experience or success with alternative practice tests is greatly appreciated.
P.S. - I'm currently scoring around a 31/32 in math and a 28ish on science based on the 3 real ACT tests I've taken. This is my first post post but I've browsed this site for awhile and I know there's tons of super smart/busy people here so any advice/help would be super awesome, thanks! :)
