Weekly examlets will be given in class on Thursdays, starting in the third week of classes. There will be two sittings of each exam, one at 9:30 and one at 10:10. The class is divided into two groups, based on the first letter of your last name.
The table below shows which time each group should report.
Before the first examlet, you must read the exam instructions and the exam logistics information. These instructions will NOT be reprinted with each examlet.
The listed chapters and skills are the new skills for each examlet. The examlet will focus on these new skills. However, be aware that you're still expected to remember concepts from earlier in the term.
Study problems should be done before the corresponding examlet. You do not need to turn in your solutions. Write up your answers, as if you planned to turn them in. Then check your work against the annotated solutions. Actually writing up the answers is important, since it forces you to work through the details and practice composing a polished proof.
Additional practice problems may be found on the Exams section of the web pages for previous offerings of this course.
You are encouraged to compare study problem solutions with your classmates, bring them into office hours to consult with course staff, etc. High-level discussion on Piazza is ok, as is discussion of very specific issues and possible bugs. However, significant pieces of solutions should be posted only privately to the course staff.
The information (e.g. skills list, study problem) for each examlet should be viewed as tentative until a week before the examlet date. We don't expect large changes but there might be small ones.
