Sometimes things just click. That was how it was when we were studying a certain chapter in my pre-calculus class in high school: it just made sense. I understood the math, I enjoyed doing the problems, and I skipped all the easy questions in the homework because I figured if I could do the hard ones, and if it all clicked, why should I bother with the easy ones? I turned in my homework assignments very incomplete, and felt great when I took the test.
The next class period our teacher handed back our homework packets: mine had a big red D written on the top. I'd forgotten that my incompletion of the assignments would also mean a lower grade.
Then Mr. Math Teacher came around again. He stopped by my desk.
"I don't understand," he began, staring down at me suspiciously, "how someone who does so poorly on their homework can do so well on the test."
And he placed my test on the desk, a big red A on the top of the page.
And that was when I realized that sometimes the grade that we get does not necessarily correspond to our understanding of the material, or to what we have learned from the course.
