Lawrence surgery: about 3/4 over the first month
NMS surgery: about 3/4 over the last 2 weeks, did the 4 question sets in the book
Case Files: whole thing, but half-hearted
PRE-TEST: whole book, then reviewed questions I missed the day before
95th percentile. Since it was essentially the only question resource I used and I had only taken Ob and peds prior to then, it can't be that bad. Obviously it wasn't my only study source either.
If you're looking for repetitive questions that are verbatim then you're wasting your time, but it covers most of the necessary TOPICS so you can review them. I agree that I would only do hepatobiliary and GI if you really wanted to accesorize with IM questions. Make sure you know trauma management and fluids/electrolytes. I tried an older edition of A&L which was TOTAL suckage (fragmented sentences, wrong answers, abysmal), so at least look at a new edition.
*Skip the effort on the nonsense questions as mentioned in previous threads.
