I went to a grammar school, but mainly because I was hard working, not smart, so I struggled a bit in terms of keeping up. Eventually I gave up trying because I didn't really see the point, so I just focused on subjects I was decent at (Music, Art & Drama, the holy trinity) and half-assed the rest.
I was sort of popular to start, but then I realised the popular people were generally just awful so I hung out with my beloved fat nerds and I'e never looked back
otherwise I was quiet, not disruptive and got involved with extra-curricular stuff too (mainly involving music, but I was an additional needs prefect also) so yeah, I was alright really tbqfh
