I got Bs in both years of algebra in high school, but I cheated some and, during tests, I had to quickly scan the test in order to answer some questions before I forgot how to do the formulas. I didn't feel confident in algebra until a math teacher at one of the colleges I was teaching at showed me how easy it was. In a couple of hours, she taught me more than two years of algebra in high school. I signed up for trigonometry but dropped out after a few days. They may as well have been teaching it in Latin for all the sense I was able to make of it.
