I'm topping up my subject knowledge ahead of September using the excellent Achieving QTS books, and over the course of the day I've become au fait with digraphs and phonemes, have learned how to identify a comma splice, and can now name you several uncountable concrete nouns. This is just the tip of the iceberg, however. There is still a considerable amount to do. I did the first chapter of the science audit test book and became very alarmed that I knew little about the science being taught in primary schools these days! How is everyone else's subject knowledge revision going?
