Most Education?

I feel like this sums up a lot of what school is.  We study to pass tests but what real world skills do we learn?...  Maybe we learn how to manage our test taking time or critical decision making skills as in narrowing down a multiple choice answer list.  Being completely honest, I will never use any formula I have learned in chemistry or math analysis.  I really don't feel like those classes were very useful besides to stress me out and to make me a more "well rounded" student....
