I question your source. The list is surely longer than this. Latin, Greek, Russian, Philosophy, Religious Studies, Economics, Classics.................
ummm if you mean you took all the subjects BBC bitesize offers revision in and decided those were the only ones available then you are sorely mistaken.Why not have look at other sources such as the government website?I myslef do both Latin and Russian at GCSE and was quite upset to not see them on this list.Please do edit the quiz as there are more than 60 subjects on offer and you have only deigned to mention 36.
Thank You.
