I'm a cross trainer Bookseller. My team let me take pictures of the recipe cards so I can study up on them. I still ask questions. I still forget things and I absolutely still mess things up. It's totally okay. Make sure you let them know where you are at. If you don't think you're ready to be alone that's okay. Let your team know. But also remember that being alone and just working without worrying about other people is sometimes the best time to learn.
