I will also be available on Thursday the 13th, from 5:30pm until at least 7pm (but likely 11pm) in the College Library Computer Lab (on the left as you walk in, across from the front desk, at the video station computers, where I will be compiling the review session video).
On Saturday December 15th I have office hours from 12-2pm and 4-5pm.
A friend, Noah Kieserman (who has been a lecturer for linear algebra) has agreed to have an office hour for me on Sunday December 16h at 10am in 420 Van Vleck as I will be unavailable that day. He is very kind and helpful, so I urge you to take advantage of this opportunity.
I (and most teachers) do not hold office hours on exam days.
If few of these times are compatible with your schedule, I urge you to go to Professor Jones' and TA Melanie Ruiz' office hours (listed on professor Jones' website)

Office Hours:

All office hours will be held in my office, 620 Van Vleck, unless otherwise stated. My office hours are at the following times, and by appointment.

Tuesdays: 12:20pm - 1:10pm

Fridays: 1pm - 1:50pm

Professor Jones' office hours are available here.

I expect most special appointments to be close to exams, and I will advertise most special appointments to the whole class as an extra office hour.

Everyone can benefit from office hours, and in fact the best students come to them to ask deeper questions.

Feel free to drop by and just hang out, though it is best to come with a list of questions. Its best to use your homework to figure out what types of problems you have trouble with and to isolate which part of the problems are causing that trouble. When working on your homework, I recommend (1) writing down the problems you don't understand, (2) going back and looking for common characteristics of these problems, (3) grouping them into problem types, (4) re-attempting the problems with your newfound knowledge, and finally (5) coming to me with well-thought out questions.


I do not have a syllabus this semester because Professor Jones has put a lot of time into his. Click here to see his website.

Have questions or want to give feedback? If e-mailing me makes you feel ill at ease, feel free to use the anonymous feedback form below.

I'm most interested in how the content is working for you, although I'm certainly happy to hear about the structural aspects of the course as well (too much discussion/not enough discussion/I'm the meanest grader ever, etc.). What content did you find interesting? What would you like to find out more about? What did you find confusing or frustrating, and what can I do to help prevent that from happening?

Remember that everyone is different and that different techniques work for different people. If only a few people prefer one way, they probably won't get their way.

I will post responses to important feedback questions here.
