welcome
Id recommend if u want to learn more Japanese to use Memrise and Busuu. (memrise in my opinion is the better of the 2, especially when first learning Japanese).
I've taken Japanese 101 in college and bc it was overall better to keep the text book(they seriously offered a penny to return it after the semester) I kept it. Its also a good tool for learning Japanese and recommend by alot of ppl learning the language, its called the book (genki/good book).
