By the way, for those who've done Step 1 already, do you think using Lippincott's alone would be sufficient for doing well on the biochem portion of Step 1? The reason I ask this is because I'm a first year med student (of a 6-year undergrad program) in Australia wanting to try the USMLE, and we've covered over half of Lippincott's Biochem in just over a week, and will most likely finish the whole thing in the next few days.

That's why I'm wondering if the Lippincott's only represents the minimum biochem knowledge that a med student should know.
I'm unable to buy the BRS/HY biochem here (I guess they're mainly for American students?) Are they more detailed than Lippincott's?
Thanks a lot!
