I'm a St. Francis alumni... Basically it's an expensive school.
Before the school moved, the discipline was rather lax - you can
play truant way too easily. But after the move, the school got
security guards for that purpose. No kidding. You're going to have
to think out a good plan in order to fool those security guards if
you wanna play truant... But that's actually good. Why pay so much
to go there only to play truant?
Teachers in St. Francis is just like any typical school - boring
and dry. But that's my personal opinion so you can choose to ignore
this. 
However, the classroom discipline was pretty doubtful... basically
you can sleep in the class and the teacher's not really going to
say anything about it so it's going to cause a lack of motivation
and inspiration and that's where you will have to look to buck up
personally.
The timetable is all right - you'd have to make frequent change of
classrooms due to different subjects so it's entirely different
from primary and secondary school where you get to stay in your own
classroom most of the times.
Anyway, what I've said, was in my days. I left the school a couple
of years so there could already have been improvements...
One last note, I paid around $5000 for a single year there. Or
rather, my dad paid. It might not be you who's going to pay but
let's be reminded that unless you are filthy rich, $5000 isn't a
small sum of money. If you are going to St. Francis, you'd better
wise up and study hard because it can be easy to get lazy
there.
