I believe high school is here to test students on their ability to work hard for something they want. I think it forces students to prove that they're willing to work hard for an academic education and that we're worthy for the work force.
I believe that the school environment lacks meaningful information a majority of the time. Constantly I notice that I'll study hard for a test, get and A or a B in the test, and no longer than a day later I forget everything that i studied so hard to remember.
