For a person without taking credential courses and never took RICA before, and without elementary school classroom experiences, which books should I need to buy? I cannot afford to spend so much, so It would help me a lot if I buy the ones that I only need. I do not have any textbook (Reading/Writing from credential courses), and do you think I need the textbook from these two courses as well as below test prep guide? These ones below (only 2 books) I'm thinking about purchasing: And one below (Text + E book) (Is it more helpful to by the one with Ebook? Is Ebook one includes video?) Thank you so much for your help!!
