I found that it wasn’t enough to understand something once. I had to practice, just like I had on the guitar. I met with professors and asked questions in class. In high school, I never went for extra help because I was in denial that I was struggling with the material. I thought only the “slow” kids went for extra help. I realized, though, that I had to put my pride aside. The goal was to do well on the test, not look like a genius all the time.
