Spare time

I have now started both my courses for the second half of the semester (the second one only started today) and I seem to have a lot of spare time. Most of my zoology courses leave me with very little time outside uni except for sleeping and eating, but it doesn't seem so with these courses. I should probably be pleased, but I'm more confused than anything. I don't really know what to do with no extra work. Ho-hum.
