How do I study recipes/xyz before training?

Hi everyone! I got hired at Starbucks and start my training the week of August 3rd. I know it is going to be overwhelming and scary going into it, but I want to maximize my success and try to get a hang of things before I start. My manager mentioned they have a new way of training for my round of new hires, and that memorizing the formula for certain drink types doesn't completely work anymore since things have changed (?). So, my question is: is there a way to start understanding the drinks and formula, and how to use the coffee machines, etc. Anything helps!
