I start at 8am and finish at 9.15pm once a week from University. Is this a bad thing? I live about 1 hour away.
I hope you have a day off on either side of that...
It'll feel like a really long day (assuming you've got a heap of classes in between those times and not just one at 8am and the other at 8pm

) but if doing that means you get a much nicer timetable, I'd say it's worth it. I know others would say it's better to have five half days as opposed to three really full days though, so it depends how you spend your time at uni.
9:15 is weirdly late, too. Make sure to time your travel schedule if you're catching trains home as they tend to be at least half an hour apart at that time of night.
