If you find yourself struggling, don't wait until it is too late. The sooner you seek help, the less catching up you will need to do!
Office Hours - the instructor is nicer than she looks :)
If you you can't come to office hours, then arrange (in person or through email) with the instructor to meet at a different time.
Group Tutoring: Attend evening group tutoring sessions with a lab assistant. The schedule will be posted here.
Individual Tutoring: If you are still struggling after all of the above, you may request one-on-one tutoring through the Learning Center.
