Not sure if the list of required stuff has changed but I think this covered everything they had on ours.
Here are my own personal opinions about these items. For the BP cuff, you can get away with only having an adult one. Any time you will be required to take a kid's BP (during Score 1), cuffs are provided.
I do not have the particular otoscope on this list. Honestly, any otoscope is fine for what we use it for. The only drawback to that particular one is that I don't believe the standard tips fit onto it, meaning you'd have to have to supply your own for Score 1 and stuff. I have a Welch Allyn pocketscope set that I got used from ebay. It's not the cheapest but it's certainly not the $600(?) one that KCU says you need. Seriously, do not buy that thing.
Don't sleep on the pen light, it's actually very useful. I used mine all the time in Score 1 and will probably carry one on rotations.
The tuning fork on this list is ass. I wouldn't even buy one tbh. You barely need it and if you do, they are provided.
Make sure you get the standard reflex hammer with the triangle-shaped head, like the one on the list. There are different styles, but you'll be expected to learn with the normal one and use the normal one for practicals.
