Each week there is to be homework set, due in the day the teacher requests.The topics for each week are listed below.
Each homework is divided into 3 sections, A B & C. A is for all pupils to attempt. B is slightly harder and for most pupils to attempt. C is the higher level work for some pupils to attempt.
