Don't worry about extra resources the first year. All of the exam questions come from the lecture notes/videos. Personally I like annotating FA, but would recommend doing it after winter break when you really start more of a "systems based learning." Anki is super useful if you make your own cards, ZAnki helps with class and early step prep but you have to comb through and suspend all the cards you don't need or else it can become a nightmare of learning stuff that you won't be tested on until second year.
Upperclassmen will have online resources (pdfs, links, etc. etc.) that are floating around and will be passed down by your big.
Essentials (that you need to get):
iPad/Tablet
Apple Pencil for quick note taking (unless you're a paper note taker)
OneNote/Notability app on iPad.
Shoes you don't mind dissecting in.
Scrubs x2 (there will be a sale in the fall if you want them cheap)
Dress clothes
reliable but inexpensive watch (last thing you want is body fluids on a nice watch)
ID holder.
Combination lock
1 standard sized 2 pewter cauldron
1 wand
Essentials (that will probably be provided to you by the school or an upperclassman):
FA
ZAnki
Netter's Anatomy Flashcards
Anatomy Atlas (not really an ESSENTIAL but so many people find it super helpful to have their own copy or pdf)
Stethoscope (if you buy your own, please don't go overboard and buy a super expensive one)
