Take a picture of every register screen so u can learn the buttons. Approach understanding the drinks by the subcategories they’re in. You have reg Coffee (hot coffee, iced coffee, cold brew, nitro) u have Espresso (lattes, macchiato, flat white) u have ur Blended drinks (frapps) and then U have Teas & Refreshers. I feel like once u know how to make each cats gory of drink, it’s all the same just different flavors. :)))

It’s just takes practice! Don’t be afraid to ask your coworkers questions!! You’ll get it I believe in you!
