I used the Fleming's Baby Bar review home study course. 40+ essays in each topic, outlines for each topic, MC in each topic, and audio cassette; great stuff. I wrote out under timed conditions 10 or 11 essays in each topic, did about 700 MC total, and issue spotted another 13 or so essays in each topic. That plus the review tapes worked very well for me.
When I found an area that I was consistently missing (partially or completely), I would study the Gilbert's summaries on that area until I had it down.
One thing you need to understand is the format that the examiners want to see answers in. I believe that, content being equal, proper format can significantly affect the grade. Studying the model answers will help with this.
I got an A.
