i just finished my a levels and you may also need lever arch folders for every subject (and dividers) depending on how tour school wants you to organise your work, so check the manual for your sixth form. otherwise i’d say, that’s all you really need honestly. if summary notes arent ur favourite method for revision (what im assuming the a5 notebooks are for), get equipment for ur favourite revision method because u will need to revise quite a lot as in a levels there’s a LOT of content and u wont have time in class to go over all of it.
hope that helps :-)
