My favorite teacher, hands down, was my high school band teacher. I didn't plan on taking band all four years of high school, but it happened, and it happened because of him. He was excellent at his job. He took a band that didn't even go to competitions because they knew they would be embarrassed by the other schools, to one that was beating schools double, even triple our size. He sparked my love for music, and I'm just happy I was able to be a part of that band. It made high school bearable, and I don't think I'll find a better teacher. Plus, he played Mario Kart with us on band trips. I always won, haha.
My least favorite teacher is a tie between my Advance Algebra Trigonometry teacher, and my French teacher. The former was just bad at teaching. She taught the math once, and expected everyone to pick it up right away. You could go in during lunch and ask for help, which she thought was enough, but the classroom was full literally every day, with students lining up to ask her a question. Normally my mom is very strict with grades and falling behind, but after one parent teacher conference, my mom turned to me afterwards and said, "Just pass the class, that's all I care about."
The French teacher just didn't fit my learning style. She was very old fashioned, having quizzes every day, and teaching a set of new vocabulary words every day. It was way too fast paced for me, as if you missed a day, you missed up to fifty new words that you had to learn in addition to the words that were taught that day. I did alright, but even if I studied an hour every day, it wasn't enough to get an A. Plus, she made me miss jazz band one day to make up a quiz. That's unforgivable.
