Yup. I went back to college when my daughter went to college. We decided to do self-tutoring math and just write the tests when we had taught ourselves. One of the professors told me that he had a masters in Math from UCSD and he had never seen anyone do math the way my daughter and I could.

Yup. I also never applied myself. I found college and school pretty boring. Also, I never really knew what courses to take and what their purpose was.
