Mrs. Zimmerman is a brilliant graduate from Stanford. However, she cannot teach very well. The only way to do well in her class is to cheat. If you wish to learn chemistry thoroughly I suggest switching classes, otherwise she is pretty funny and it's a fun class overall.

Dr. Zimmerman is a smart lady, but when it comes to teaching the class, unfortunately she cannot teach to the whole class. She has a PhD in Organic Chemistry from Stanford, which is impressive. But I wish she would teach more because a lot of what she says and does is very collegiate-like. In terms of her tests, they were hard for most of the class because of her lack of teaching all content. If you want to do well, spend an hour or two reading the chapter before a test and you'll be fine.

She was the worst teacher I have ever had at IHS. She does not help with AP Chemistry at all. People cheat in her class all the time, yet she thinks they consistently perform well that she believes they are just naturally smart. It's obvious the kids are cheating because they have their iphones right next to them, scrolling through with the answers. Not only can she not teach, she is a mean person herself. She would call you to the board to answer a question on new material and laugh at you.
