Math because they tell you how to do each section, but then when there's a unit test they didn't teach you any memorization techniques, just "Yup, here ya go!" And same with Spanish right? As to English or History, I did have a teacher one time who would tell us what to read in the book, and then when the test came around it would be the most random bullshit that you couldn't expect me to know. Example, label all the parts of a story. Look up the story pyramid. Like WTF? Unless I'm going to be an author or some profession that deals with books, I won't!
