Exams: There will be two exams, of which your lower score will be worth 35% of your grade, and your higher score will be worth 40%. Exams are to be exclusively your own work. In-class exams will be closed to everything, save for one page of your own notes. Exams are scheduled for 10/18-23 and 12/6-11. No make-up exams will be given except in extreme circumstances.

Quizzes: These will be quick 20 minute in-class affairs. Closed notes/books/etc.. We will have about five of these in total, coming every couple of weeks, except exam weeks. Quizzes are tentatively scheduled for 9/6, 9/27, 10/11, 11/8, 11/22. No make-up quizzes will be given except in extreme circumstances.

Homework: Regular homework will be due on Wednesdays in class (unless otherwise specified due to weird scheduling), based on the previous week's material, and will be posted below. See "Writing guide" below for stylistic guidelines and tips on getting started with LaTeX.

Academic integrity: On exams, as mentioned above, do not discuss anything with anyone who isn't me. Doing so is considered cheating. On homework, however, you are welcome and encouraged to work with each other, and to talk to me while solving homework problems. You are also welcome and encouraged to proofread each others' homework write-ups. Your write-ups should be your own, though, and final drafts should be written on your own. Of course, this class is covered by the CUNY Policy on Academic Integrity. See also Richard Neidinger's Avoiding Plagiarism in Mathematics.

Course expectations: I expect the following from you throughout the semester.

1. Before class:
   • Skim the listed reading for the week.
   • Review your notes from the previous day's class, making notes of any questions you still have.
   • Print out the day's "handout", or bring a device on which you can access it during class.
2. In class:
   • Come to class! If you have to miss class, spend the extra time reading the book and note outlines; contact a classmate to get the rest of the notes from that day; and contact me if you need to miss more than one day.
   • Participate! Ask and answer questions, and work actively in groups on in-class exercises.
   • Hand in homework every week, on time, and in final draft form.
3. After class:
   • Now, really read the listed reading. The book is called "friendly" for a reason, and the notes posted here are not generally complete!
   • Come to office hours at least once this semester. If you can make the regularly scheduled time, just come. If you can't, make an appointment! To do this, mention to me in class that you'll be sending me a scheduling email. Then follow up with an email requesting an appointment, including your available times, and what you would like to discuss.
   • For every hour in class, you should be spending about 3 hours outside on reading, homework, etc.. For this course, that means 7.5 hours/week.
   • Spread out your homework throughout the week, so that you have time to ask questions before it's due. I expect many of the exercises to be challenging, and to take time and work to get through—it's ok if you get stuck! That's the point! Take some time to puzzle on things on your own, and then team up with me or your classmates to chip away at it. Of course, this process takes time, so don't put off starting it. Here's a great article on the importance of getting stuck in mathematics.
4. In general:
   • Communicate! If you're confused, lost, swamped, or whatever, say so. Even if you don't know what questions to ask, let me know you're missing something, and I will try to get you back on track.
   • Get to know each other! Your classmates are some of your best resources. Talk to each other, work together, explain things and ask questions. If you don't have time to get a study group together on campus, find out who else lives or works near where you do, and make time that way.
   • Be honest and work with integrity; if you slip up, come talk to me and we'll work out a fair way to proceed.
   • Have fun! Number theory can be challenging, but it's a fun topic. Learn to play with the ideas: generate data, make hypotheses, and prove results by explaining why things are true with precision and style.
