Off to Barcelona

My son's got a big maths test tomorrow (his mock GCSE). He needs to get at least 80% in order to be able to sit his iGCSE a year early this year. I sat down with him and did some revision in the morning. I think he'll be ok but he needs to get into the habit of reading the question properly. He often gets the answer wrong because of this.
After lunch, hubby dropped me off at Heathrow for my flight to Barcelona.
