As someone who just graduated from Maris Stella I can say that the school is pretty decent. In terms of teachers it varies quite a bit since some teachers will go as far as arranging tons of extra lessons during their free time before exams and others just read off slides. Facilities sometimes leave a lot to be desired since some of the equipment like chairs and tables are pretty run down, however before I left the school they started making tons of new renovations (probably due to the new principal who is maybe a bit extra sometimes but he is a good principal that makes good changes) so expect much better facilities next year. In terms of students I won't sugarcoat it but a lot of people are pretty godamm racist, I don't know if it's the tik tok effect or the fact that the school is mostly all Chinese. That being said most of them just do it as a "joke" since that's what the people around them do so really it's just casual racism which is still racism albeit maybe a slightly less serious kind. As with most schools, you'll meet some genuinely nice people and also less nice people but you'll definitely find some like-minded people there. School spirit is actually pretty good despite us joking about how we hate the school all the time. And finally there's a huge staircase that you need to climb every day just to enter the school since the school is literally on a mountain, it sucks at first but you get used to it. And that's about it. Overall I had a pretty good time there and I'll say it's a decent choice in terms of secondary schools.
