I used tutor mode for all my 50 questions sets. Each set was from a particular section that I was studying for that day. I.e. Heme-lymph only, g.i. endocrine only, etc.
I would highlight/answer the question to the best of my ability, then I would look at the answers/explanations. Then look at any tables/sections in my review books that pertained to the subtopic. That way I was reinforcing each clinical vignette from Q-Bank with hard cold facts and details. Any explanation deemed worthy from Q-Bank would be written into FA notes section.
I would not change the answer though I may have gotten it wrong. At the end of the 50 question set for a given subtopic, my score was usually dismally low (40%). I would then do a non-repeat of 50 questions in the same subtopic, and would repeat with the review style. Repeat and Repeat again. Then when I used all the non-repeat questions, I would go back to the questions I missed, and create a test from them.
This was usually a full 8 hour study day for each topic. The vignettes helped give me context to memorizing the tables, figures and facts out of FA and BRS Pathology. It was a good synergistic interaction.
3.5 weeks of this and I felt pretty good for the boards. 236/95.
