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.
