hi samar
i suggest u study in the book our college gave us, i think it's called armstrong, it's really good, i studied in it and u will have much better knowledge than what the stupid lectures can offer. some copies r better than others, so if ur book has bad quality photos, exchange it for a better 1.
as for the oxford handbook, don't know about the surgery but the new medicine oxford handbook has been in the market for some months, i got it, it's cool.
