The third exam takes place on Monday, April 23. As usual, information on the exam can be found here, which includes the list of topics and a link to the study guide.

The topics covered will be those since the previous exam and include the following lectures:

I also posted a review of last year's exam questions

Like last time, I will be grading the multiple choice questions automatically, so you'll have a separate entry sheet. Please bring a pencil to the exam. If you're confident about not making mistakes, you may use black ink or a marker. Also, be sure to have your RUID number. At least two of you didn't write your correct RUID on your submission last time.

The second exam takes place today. To help you with last-minute studying, I've put together a few slides that highlight some of the cryptography and integrity concepts we covered. They are not a substitute for the lecture slides and study guide but can serve as a last-minute review. I also crossed out some topics in the list of topics so you can focus on the more pertinent topics.

The exam will follow the style of the previous one: a few short-answer questions followed by a bunch of multiple-choice questions. For the first time, I will try grading the multiple choice questions automatically, so you'll have a separate entry sheet. Please bring a pencil to the exam. If you're confident about not making mistakes, you may use black ink or a marker. I did not test the software to see how robust it is with different ink colors. Also, be sure to have your RUID number.

To help you prepare for the exam, please check the following resources: This has been up for over a week but I fixed a lot of typos and some omissions in the lecture slides, outline, and study guide (e.g., added a discussion of hash pointers to the study guide). I also changed some file names, so be sure to refresh your browser when downloading content.
