I have it. Its ok. Some of the ?'s are way tooooo vague. Explanations for ?'s can give great inside while others you are wondering WTF... They test on high yield as well as very very low yield stuff. I have mix feelings about it. For step 1, its great in combo with kaplan qbank. That is why I chose it. For step 2, ahhh. Just stick with UW and Kaplan.
I give it a 2.5-3 out of 5. Its cheap to buy, which is always a plus. Using it as a primary source, Bad idea. Second source maybe. As a third source definitely. Like I said, They have very good ?'s with great explanations, but there are ?'s that are mediocre or WTF. So its up to you. You have the time, why not.
