Does her school not offer 'clinic' sessions to help students who are struggling? Has she flagged up with her teacher the areas in which she feels she is having particular problems? (Although more to the point, how come her teacher hasn't noticed?).
I spoke to her maths teacher today - a new one who has not had her before. I asked about revision sessions. She said there is nothing particular for GCSE, but there is a session, she thinks, when the maths teachers are available at lunch for anyone who wants to come along. She suggested DD bring in her textbook or revision book and that she would indicate which topics have already been covered in Year 10.
I like the look and calm clarity of the Hegarty Maths videos. I'm already enjoying e-learning Spanish and German to keep the children company, and now wish I had the time to do GCSE maths too. Lucky generation to have these resources.
