Over time we are put in touch with projects similar to this one, only with a different flavour. There is overlap, but one can never have too many pearls.
AlmostADoctor.co.uk is a fantastic resource with loads of notes, mindmaps and blog posts that you can help contribute to.
In terms of emergency medicine for students, CDEM has us covered.
MosaicEd.org is well worth a check out too, not just for emergency tips, but all specialties get a mention.
Common Rounds also has podcasts aimed at student level, as well study resources available.
You know of another one? Let us know, and share the love.
