**Old 3120 exams are listed below. Each exam is followed by the solutions to that exam, and most of the Unit II homework problems were drawn from old exams. Fight the temptation to look at the solutions before you make a serious attempt at working the problems. I will provide an exam-to-homework decoder ring later today. And don’t forget that Harris contains many good and relevant homework problems. The problems and solutions from Harris are posted above.**
