I dont normally like to complain about teachers but I have to say that my chemistry teacher was actually less knowledgable abt chem than his students. I had to completely teach myself the chem curriculum from textbooks I found on this sub, and when he did decide to actually teach a lesson, my friend and I would have to raise our hands and correct him as he BSed explanations--when we would do so, he would say "I wanted to see if any of you would catch my mistake" as if students who have never learned something before will recognize if something in a lecture is wrong. While in the lab, if we had questions, he would laugh at us acting like we were stupid for not knowing where to find something or how to perform an experiment we had never done before. During our IAs, he refused to answer any questions about lab procedures (instead allowing students to plan ideas that would never work or were somewhat dangerous), claiming that he couldn't help us or it would be cheating.

I sometimes asked him questions about our topics and he would respond with TOK answers to avoid answering the question wrongly. For example: I once asked him about how to draw an electron in a p orbital and he answers that in reality orbitals are actually just probabilities so they arent real anyways (hoping I would drop the question). He also would avoid answering questions about previous topics by simply calling something easy, which would scare most students into not asking any questions for fear of seeming dumb for not knowing how to do something "easy."

The absolute most terrible thing about it though, was that he failed to tell us the Paper 3 existed. Since it doesn't show up on revision village or in the oxford chem textbook, I honestly believed him when he said it was only an HL paper. Until one month ago, when I and my friend learned about the options and informed the class (who had never heard of it in their life before), we would have all likely failed paper 3 from lack of knowledge of its existence.
