Be thankful you didn't use it for step 1. I did and did worse. They throw the big caveat in at the beginning that their course only works if you use first aid and usmle world on your own time as well. Basically, they are saying that if you use first aid and usmle world (which is all you need for the exam), you will do well. Well, uh.... duh. The problem is that the videos and workbook take so long to get through that you don't have time to do usmle world and review first aid, so you don't do well. Additionally, you don't have any time to review any of the stuff they go over. Basically, you spend three weeks doing a first pass over all their material, and none of it sticks. You're then left with a few weeks to cram first aid. Better off just doing first aid and uworld from the beginning. Their concept is good, but it is totally incompatible with a 4-6 week study period most people have, and robs you of valuable qbank time. If you have a few months, go for it.
