An excellent teacher. She doesn't tolerate trouble makers.
Listen to what she says. Best piece of advice ever. She really really really! knows what she is talking about. Brilliant teacher, can come across like a difficult woman, but seriously, if she gives you notes, take them word for word, if she gives you homework, do it. very recommendable! Physics is a difficult subject and you just need to take the time to listen to her and learn your stuff! this is the woman to help you.
