There are some teachers at plum who deserve the highest ratings, and some who shouldn't even be teachers. I would say the majority of teachers help students who struggle, are available outside of class, and genuinely care if we succeed. However, there are quite a few teachers who don't care about the class at all and barely even understand the subject they teach. For example, I had a math teacher one year who made the class very interesting and challenging, and was always there to help, then the following year a math teacher who had simple math mistakes on half of his solutions, and was so bad at explaining that I ended up tuning him out halfway through the year and instead taught myself and a few other classmates. I think the biggest problem I've faced is a lack of interest from the teachers in helping with school clubs and blatant favoritism. Some teachers are very involved with clubs, which helps make them lasting and fun, but there are quite a few clubs that have no support because the teachers willing to help don't have the time, and the teachers available refuse. Dealing with favoritism, there are a lot of teachers who make it obvious who they like more, which is reflected in their grading and availability to help. For example, one of my art teachers has been giving me feedback on my AP summer work to help improve, while one of my friends has not received a single email in reply for her work.
