i feel like Jude would be a little above average since he loves science stuff and good at learning new languages but he would be worse at stuff like english cause he's dyslexic as well (i had to give him my entire academic background), Fio on the other hand would ROCK english and maths but be a pretty average student due to lack of interest in other classes, also she would love P.E since she likes running while Jude hates it (from my experience. AGAIN 😭)
