Haha I think this all the time! I graduated 15 years ago (English and History) and can barely remember a bloody thing. I somehow managed to get a First, but it appears my skill was rote learning and not actually digesting and retaining the knowledge
I remember sweating blood and tears over my dissertation yet I can’t even remember what it covered aside from the bare bones!
Similarly, I couldn’t tell you the most basic shit about my A level topics, and despite French being one of my best GCSE subjects I’d struggle to hold a basic conversation in French these days (can you see a pattern here?!)
It’s actually rather depressing that a whole childhood / adolescence of learning amounts to very little retained academic knowledge in my case! But maybe it’s just me 🤔
On a slight tangent, I sometimes think much of the curriculum (at least back in the 90s) focused on the wrong thing. For example geography - endless learning about volcanoes and rocks (which you will generally never need to know about as an adult) but no teaching of the basic geography of the world.
Similarly back then there was no economics, politics or ‘life skills’ which would’ve been really bloody useful down the line! We didn’t even have proper sex education at my school, just a brief mention of anatomy and periods in Biology! Luckily the scope of subject options seems a lot wider these days ...
Sorry OP I got a bit carried away there with my angst over my mis-spent education 😂
