I just taught a course on Insurance Billing and Collections and the biggest complaint was difficulty with retention. The textbook contained alot of information and that was frustrating to them. I suggested to my students to break the studies into sections. I told them to make sure to have good notes from the lecture and every night to review their notes and try to read the section in the text which corresponded to my lecture sot that they wouldn't find themselves reading the whole chapter the night before class. The could re-read their class notes and skim through the book. The class found this very helpful.
