First of all- don't worry, you are going to do just fine- you are already sooo ahead of the curve being so prepared before class! I did the same thing- getting the book early b/c I was so freaked!!
What really helped me in Anatomy was videotaping on my phone going over the model figures with my lab partner. A lot of students have done this and posted on youtube. I would watch those over and over again at home, because even though everything is in the book, on the practicals we were tested on the same models we studied with in class.
I would also go to the tutoring lab and record a tutor going over the model for me and then try it myself with the tutor again and again, then go home and watch the tutor version to cement it.
I'm someone who needs hands-on studying so it really helped me for the practicals.
Physio- I loooove concepts, so I was really fascinated in this class. Whenever I had a hard time with something (it took me so long to really get cellular respiration to the point where I could teach it b/c I know it so well)---
I would go to kids science websites where they break stuff down really simply, then I would go to my favorite learning website EVER-
Khanacademy.org --- he breaks physio concepts down so well, I swear this site's saved me before a test a million times! They have a ton of subjects that are lectured on.
I don't think a lot of people use teacher's office hours, but I strongly encourage you to get to know your teacher, befriend them and make use of the office hours. I've found that having a strong relationship with a teacher who knows you are really putting in the effort can go a long way. Later in applying for stuff, you can go to them for recommendation letters and advice.
I've also emailed my science teachers before classes started as well, just introducing myself. It's a good start to class, then they already have heard your name on day one and keep an eye out for you.
I strongly encourage you to really lean into this knowledge- I just took the TEAS and it's allllll on the study guide! Not to mention the fact that we will use this info to help others the rest of our lives!!
Oh, and GOOD LUCK!!!
