Clerkship resources

For those that have gone down this path before me -

I am looking for reliable, sufficient resources for prepping for my wards.

There are a ton of books out there and each one claims to be the best text for that particular rotation.

I start IM on Mon. and am completely lost on what to buy. Step Up, MKSAP, Secrets, Case Files, Wasington U. Pocket Manual, Mass General Handbook and the list goes on.

Any specific recommendations? I’ve heard First Aid for Step 2 is not that great.
