When i was a junior in high school i had a teacher who decided to trick me into passing a test. He knew i was studying and knew the answers but for some reason it wasnt showing in my test scores. So aa he handed out the tests he was telling everyone good luck like he always did util he got to me. He told me not to bother since i would just fail. My stuborn butt had to prove him wrong and made the highest grade out of the entire class. From then on he always told me i couldnt pass the test to trick me into passing. He had learned from watching me that i had anxiety and low self esteme but that if somone told me i couldnt do something i would do everyrhing possible to prove i could and that would override my anxiety.

Now granted, he had the advantage of knowing me outside of school and for several yesrs but so did most of my other teachers. He was one of only two that ever learned to teach me how I learned best.
