Hello students.
I need to aplogize for the chaos regarding grades these past couple of days. You can imagine how insane I feel trying to get this all sorted out. I know this is very nerve racking for you, and I want to make it as painless as possible from here on out. Additionally, bc of a personal emergency, I wasn’t able to update the website as regularly as I had hoped. Since the CVHS server won’t let me on at school, I will do my best to update the website as soon as I can, which is usually around 5pm. Again, thank you for your feedback. I look forward to teaching you the rest of the year.
Ms. Yi
