yep,
had a class that gave me a 4 hour break,

had to go to school at 7:30am to open the library,
had about 3 classes after that,
then at 2pm i had a 4 hour break because that particular
class was only provided for that semester and those classes
were only available at night from 6pm-10pm.

those were some busy school days.
and didn't achieve much from it.
but I graduated........and thats about it, never got a career out of it,
just a huge school bill that never got paid and living almost completely on
freelance work.

but my point is, yea I know that feeling. lol.

I usually have my laptop with me so I can always have something to do.
