And is it even feasible for someone at non selective state school?
DD is at state school. It's our local one and used to be a sink school, just achieved Ofsted Good and we are very happy with it. DD recently diagnosed dyslexic but as expected progress for grade 7+ at GCSE (only lower is maths at Grade 6). Absolutely loves ancient history and mythology, particularly Greek. Starting to excel in art as well. Pretty decent at French but hates it.
I'm assuming Art, History, RE and French would be good options? Is it a no go if no latin before uni? DD has wanted to study history at uni for years but when I told her a whole degree subject exists for ancient Roman/Greek culture she got a little bit excited. Me and DH are ex poly graduates in vocational subjects so this is not a world we know about.
