Is functional account of mental states correct?

Finished my A-level Philosophy with an A, so I thought I'd share some of my essays that I still have so someone else might benefit. Please don't copy it but use it as an example or inspiration. Been there, done that and I'd honestly kill for those things back in the days. Also pls keep in mind that English isn't my first language so some phrases might be weirdly written. Good luck with your exams, you've got this. I swear it only gets better from there.
