Important Information Regarding PTA Codes
Please be aware that I cannot give PTA codes to students on the waitlist. Please do not email me to request a PTA code if you are on the waitlist for either of my classes.
Please read the information on the UC Davis Math Department's webpage, linked here, regarding when it is appropriate to request a PTA code.
Since students often sign up for more classes than they plan to take, and/or rearrange their schedules after the start of the quarter, it's likely (but of course not guaranteed) that some student(s) will drop the class and students on the waitlist will be able to enroll. If you're still on the waitlist at the beginning of the quarter, you are welcome to attend class up until the last day to add/drop in case seats open up in the class if currently enrolled student(s) decide to drop the class; but I cannot otherwise accept students off the waitlist.
