Book an appointment with me during office hours. See the "Office Hours and Tutoring" page linked to on the Canvas Homepage. All meetings are virtual. During our meeting, you can introduce yourself, tell me a bit about your background, and any concerns you have about the course. This will help me get to know each of you and give you a chance to practice booking an appointment so you know how to do it when you need to later in the semester.
Can't change a rubric once you've started using it.
