@jumbopanda there is a nursing forum here worth visiting to read what other students are asking as well as to ask your questions to a more focused audience
I hope you have been earning good grades so far which is important not just for admission but for eventually doing well on the NCLEX. Aids include things like anatomy coloring books, index cards to quiz yourself, review books, etc. There is a book “Make it Stick” worth getting from the library and reading over the break; the book talks about learning and has lots of tips for HS and college students
