When I went from junior high school to high school, my math teacher had to make a recommendation for what courses I should take. She overestimated my math ability, and she had me skip some courses that I really should have taken. I managed to squeak by in Algebra 1. Then there was Geometry. I loved this class. Measuring angles and shapes made sense to me. But then I had to take Algebra 2. Here I ran into trouble.
