Yes, definitely check with your local library or see if you can get a study guide on interlibrary loan.
The test is is very basic, I believe it tests at an 11th grade level. Of course, for many of us, 11th grade was a long time ago! If you have a full month to study, you should do completely fine. I registered for the TEAS on a Thursday and took it on Tuesday. I read up on some basic chemistry and physics, and didn't study for the english and math sections. I scored very high.
There is a website that can help you "diagnose" which areas to study - www.tesprepreview.com
. If you go to the nursing entrance tests, you should be able to take little mini-tests for each of the sections that lets you know what to study. If you score 20/20 on the math and 15/20 on the science, you know that you can focus your time on brushing up on science and you'll be fine.
