I have one KS3 class that I absolutely dread every lesson. It baffles me how much they can impact my mood or my enjoyment of lessons. Not a dilemma as such but I am getting fed up of feeling like I'm fighting a losing battle and getting teary after every lesson. I'm a bloody good teacher, if I do say so myself, and I've had tougher classes than this lot. I just can't work it out.
