And that's why I only tutor 1 person in A-level maths. They know I did A-level many years ago and am out of practise. The pupil started this September and he texts me during the week so I can get some reading in!! It's actually been pretty good - I am able to support him and push him along. I do have a pupil who is doing A-level physics and has asked me to support him with the maths for it. Again - he texts me and we work together so he can practise what he's learnt. I've done some physics but use my mechanics knowledge to help me. There is no way I could wing it in an area I do not know - would be too obvious!!!
