Katherine - B- - very quiet student, did well when she applied herself (in her favourite subjects) but was mostly average
Beatrice - B - a very hard worker in school, but struggled to get higher than mid-average results

Henrietta - C+ - coasted through with the bare minimum
Percy - A - had to work really hard for it, but got really good grades
William - A+ - extremely hard worker from a young age, exceptionally intelligent, top grades

Alexa - B+ - on the higher side grades-wise, could have been exceptional if she applied herself but she did not
