Help studying

[Lynker, LPN]

So, when I took my TEAS test for the LPN program, I passed it with flying colors. I took it for my ADN after I finished my LPN and bombed it. So, this shows I need to study more. I have the official TEAS test book, and I've been using free online tests. Does anyone have any other tips or tricks on studying for it? I'm having trouble knowing what to study for.

Edit- For the school I'm going to, I need to pass with a cumulative 62%. I failed it with a 59%, mostly bombing the science portion with a 30-something %.
