Classmate, if I hadn't seen your question, I wouldn't have known what Autopass was. Hereby, I also went to see Quantong specially. I found that there are few bookstores selling Autolink, and they are relatively basic, which is not helpful to improve their grades. If you want to get points, I suggest you buy a glorious book. I have used this book, the content is well written and the explanation is comprehensive. If you can use it, your grades will be greatly improved. Personal suggestions, hope to adopt! ! !
