I had some teachers who cared and some who don't. The one I caught playing Snood usually let us goof around on Fridays during our labs unless we actually had a lab to do. XD
Wish I could of had that year I had too much homework. Like seriously having on class give me homework once a week is fine but having homework for each class every night is ridiculous.
Seriously how much are you really going to need after the basics in everyday life. Am I really going to need to figure out the Circumference of something unless I work in a field that needs it. >_>
