Favorites: Photography, Science and English.
Least favorites: Math and religious studies.
I went to a private Christian school and we had two hour religious studies every day where we had to memorize the Bible and it's seems irrelevant when that time could have been used for something useful. I'm not saying religious studies are useless. I like to learn about them, but all of them. Not just a two hour slot where we are preached at and forced to memorize a book.
My favorite was English because it allowed me to be at least somewhat creative and expressive with my opinions and writing.
Another favorite was photography class. I liked expressing myself through images but the downside was our teacher was usually not even in our class and we mostly played DDR and other games he left in there for us to do.
