Hi We have just switched to IGCSE Maths and consequently have about 125 relatively unscathed copies of Oxford GCSE Maths Higher ISBN 0199150893 which are now redundant as far as we are concerned and taking up cupboard space. We also haveseveral teacher's books and some of the homework books ISBN 0199150818 . Also we have varying smaller numbers of the Oxford framework maths series books 7,8 and 9 in core, extension and support variants. Typical ISBN 0199148600. We would be delighted to find a new home for them.
