I am a healthcare worker considering whether to retrain as a teacher. I have A levels in Biology, Chemistry & Physics and a healthcare degree. I would probably choose Biology if I were to teach science. I feel I would prefer Primary teaching (I find it easier to interact with primary ages, but this may be because my children are that age) and I would love to feel I'm 'making a difference' in the early years but realise this is probably naive.. Would love to hear pros and cons of both please.
