Any tips on studying for the science portion of the NLN / PAX-RN?

[elimabeans]

I took the newly-updated test yesterday and got a composite score of 145. The verbal and math sections weren't too bad, but I found the science extremely difficult (I placed in the 86th percentile). Does anyone have any tips or study guides for studying the science portion? I can't remember exactly what was on the test, but I know it had a bunch of plant questions I knew nothing about.

Some students had some technical issues during the test, so my school is making all of us retake it in a few weeks. I want to make sure I do better on the science section for a better overall score because they're only taking 40 of us.

Any help would be appreciated. Thanks!
