Good Afternoon Heather,
I'm so glad to hear you're excited about the upcoming year -- I am too! I really want physics to be a class where you can relax, let your guard down, enjoy what you're doing, and focus on learning and exploring instead of worrying about grades -- we haven't talked about it in detail yet, but my whole grading system (I call it Skills Based Grading, or SBG) is designed to minimize the stress of grades and allow you to focus on what you know and what you need to work on. We'll figure it out and with a good attitude, we'll have a great time this year!
