I went to a private (small!) Christian school and I had the same teacher for all 12 grades. I will not say anything about her, other than the fact that it was too much for her! When I was 15, I started working for a produce farmer that lived a mile away. I got good grades in school except algebra, and he spent MANY lunch hours and MANY evenings at our house tutoring me. It was because of him that I graduated and got my diploma!
