What about books about future education?
I took the Level 2 exam in September of 20 13, and it was also a paperless all-machine exam. At that time, I also used my exercise book for my future education. Personally, I think the content in the CD is more important. There are fewer original problems in the book, but there are many in the CD. I took the second grade exam again this year. Anyway, his sophomore questions are still very accurate, and those who report to class outside also use the contents of his disk. As for the third grade, I don't know much about it.
