The TABE is a review of stuff you learned in hs. It's also the test people taking GED courses have to take in order to "graduate." TEAS was more intensive. I ordered the study guide from ebay, but the book and the test don't match exactly. We're in our second week of classes and as a wife and mother who also works AND studies, I can tell you that it's going to take some getting used to as well as some serious time management.
