Hi, Strange request really - the situation is that I am an older teacher who obtained 'O' level maths in the late 70s. I have 20 years experience of teaching at KS2 and I also privately tutor children in years 5-8. I am now in a position where I am about to tutor a pupil in Year 9 and I feel that I need to update and refresh my maths knowledge at GCSE in order to be competent and confident in tutoring at this level. Trouble is, there is no opportunity to study GCSE maths at intermediate or higher level where I live and I think I would find foundation level to be too easy. Would it be possible/sensible to try to teach myself from GCSE textbooks do you think or is there some other way to improve my skills? I don't necessarily have to obtain a GCSE, just be confident at this level. Many thanks.
