One of DS's teachers has suddenly started setting LOADS of work. It's all online, nothing he has to generate himself. Think a quiz type system. We're struggling to keep up with the sheer volume and I've asked the teacher to give me a call. I want to understand if this work is going to be covered again as it feels like he's trying to squeeze too much work in.
He's replied to say when he will be available for a chat. What do you think is an acceptable time to wait for a return call from a teacher?
