I bought the flash cards and ended up tossing them in the recycling bin: the free online version is so much easier. You toggle through the cards and if you pick the wrong answer, it highlights the correct one. My wife spent about three hours online and passed the test....she had zero background in this stuff (I didn't either, it was more alien to me than general chem in college).
If you spent two hours with the online version this afternoon, you could easily pass the test tomorrow morning.
That's the site I've been using (from your other post) and the "flashcards" I meant. I checked out the site, got the first one wrong, and went and got the book. I've been alternating between hamstudy and the book and have been doing a bit better.
