Economic & Public affairs.
I did it for O level instead of Latin (which the careers person said, wrongly, I needed for my prospective course at Uni) but I wanted to be with my friends & so I took EPA.
Taught me to be open -minded, gave me a grounding in how monarchy, parliament, the justice system all link together & also taught me a lot that's been helpful with personal finances.
Like quite a few of us, I could read a little when I started school, & if I hadn't been formally taught maths, I would've signed up to learn it, ,but EPA was a wild card & a real help.
