[Hitchhiker 42]

Our team runs the first 2 weeks like so:
Mon-Thur 3:30-6 unofficial, 6-8:30/9:00 officially
Sat 9-4:30

The last four weeks get a tad bit more intense:
Mon-Fri 3:30-6 unofficial, 6-9:00 official
Sat 9-5

By unofficial I mean that when homework is done, students get right into work, official is the official meeting when everyone is there. The more dedicated students go 3:30/4-8:30/9.

Officially, this works out to about 20.5 meeting hours per week, plus 12.5 hours for some students working when they can.
