Or you could not be a gunner and either have some fun or make some money or both before 3 years of studying like hell starts. Trust me, in the grand scheme of becoming a PT, memorizing random bits of anatomy before school starts will literally make no difference at all. Maybe it will make your first 10 weeks of school ever so slightly easier, but that is like 1 iota of all the crap you are gonna have to learn in PT school, and it probably won't be your hardest class anyway. A good third or more of what you memorize will be different than the way your anatomy professor wants you to learn it anyway, particularly when it comes to muscle attachments.
There really needs to be a giant sticky or better yet a big flashing banner at the top of the page telling people not to worry about this topic. Let your pre-PT neuroses subside people...you're in...it's all downhill from here, so to speak. 😉
