Here's mine:
Monday: No free periods (except lunch) 8:10-2:25
Tuesday: Period one free (FUCK YEAH) 9:00-2:25
Wednesday: Double free

8:10-12:45 (but only have 3 classes in that time)
Thursday: Period 8 free

8:10-2:25
Friday: One free (which makes a double lunch) 8:10-2:25
My timetable is prety good for my school because most people have 8:10-3:15 on thursday (which is painfull) but I get to leave early at 2:25

Also, that tuesday period one is awesome.
1) Overall, it adds up to 5 free periods a week
2) 50 Minutes (except period one and two on tuesdays which are 45 minutes- cos assembly is tuesday [but not many people go])
3) We can come later, and we're not supposed to leave early but they're never gonna stop you.
4) well, i have one double, one double lunch and two frees that I can spend at home (p1 or p8) so I suppose I'll spend the seccond part of the double lunche in the library (what fun is lunch by yourself?), spend the double free in the library too... and go home for the other two. But a few mates also have my free blocking, so that could get in the way of library

5) 5 a week

I'll have to aim not to do anything stupid at school on a monday or a tuesday, otherwise they can keep me back in detention on thursday (thus relieving me of the chance to go home early).
