I used that "Chinese Made Easier" series of textbooks and found that they had a pleasantly-gradual increase in difficulty. On the other hand, at another school, another time and place, I used the Boya series. I remember a big, sudden jump at one point in the second or third year. It was as though Team One wrote the first few books, then handed the project over to Team Two without much collaborative discussion about the various levels. Threw me for a loop and took a while to overcome. Lots of tearing my hair and swearing ensured. Fortunately, I had a good teacher.
