She is one of the worst teacher out there. I am an AP student so i know a lot of intelligent teacher who know their material and are excellent at teaching, she is most definitely not one of them. She shows extreme favoritism toward African American and athletes. She expects you to master the whole lesson based off of one simple example. And she offers a lot of after school tutoring, as if that would make up for the confusion in class. She definitely did not prepare me for the AP test.

By far one of the most difficult AP courses that I've taken, she is erratic to say the least. Offers an extensive amount of after school tutoring as if to compensate for her lack of actual teaching capabilities during class. Usually does one example and expects students to fully understand that concept thereafter. Don't take AP Physics.

Worst teacher i've ever had. I'm an honor student so I have been around many AP teachers, and she's by far the worst. COMPLETELY unorganized! Does not teach at all. She expects you to just go home and teach everything to yourself. Dont take physics.

she's tough, but fair. She is more than willing to stay after school and help students out, and I think that is great.

Miss Gerdes literally LIVES for AP Calc, AP Physics, Academic Decathalon, & for her students. As a person, she is very trustworthy & you feel welcome to talk to her. If you have problems, go to her for help & study w/ her! GL
