Things not To Learn In school

I have learden a couple of these traits, but the biggest one that i've "learned" would be that "you only need to get a 70." Over the last few years i have been doing only "okay" in my classes, just getting a C in order to pass. All that i wanted was to make sure that i got all my credits so i would be able to graduate. That has been my biggest goal just so i would be able to get my own job and move out.
I also have been stuck with the "you only need to know what's on the test." I have almost never studied for a test, and whenever I do I only look at the material that will be on the test and afterwards not give any of that information a second thought. I know that's not the intention or purpose of a test, but that's all that it is to many kids. Which is probably because of the last thing that i wasn't supposed to learn in school.
"It's the teacher's job to teach you stuff" is probably the second biggest thing that i "learned." Like I mentioned earlier, I never study for tests, so i rely on the teacher to teach me the material.
