The new intensive textbook is the textbook of Liu De Training Department of Tongji University. This kind of teaching material focuses on training in the shortest time, so it is very difficult and intensive. I have learned two volumes and six texts in one unit (including listening to fill in the blanks) in my junior year. The glossary is compiled in a separate booklet. Basic grammar is covered by two volumes, and there are exercises, which are suitable for short-term surprise study.
For example, the second volume of New Refinement (the first semester) teaches passive state, while the newly compiled College German is the ninth lesson (or 10) of the third volume (the second semester of sophomore year), with fast grammar.
