I read them 2 days before my test. Thought it was worth it. Don't have a score back yet to verify that it was a good idea, but I remember a few questions from the notes in my test.
Pestana notes refer to surgery vignettes by Pestana. Supposedly they are available as some lecture PDF but I know them as the Kaplan Step 2 CK surgery notes. Find the 08-09 edition, they are updated compared to the 05-06 edition.
