Although my class is listed in the schedule as single-level Beginning High, I have in essence a multi-level class because of the differences in students' knowledge and skills. This has been the case for 3 years. Other teachers have told me their classes have the same quality.
The best you can do is try to keep a positive attitude, and plan your lessons so the high-end students are always busy, even when they finish ahead of the others.
