Ew, school. I hate these years because teachers made my school days a living hell, and I still regret that I didn't manage to learn anything important there.
Feel you. My French teacher didn't like me at all, and I still don't know why, so I didn't go to his classes. I thought it was fair. Too bad that I didn't learn the second language at school, so I had to use some help from a tutor from https://livexp.com . Now I know French, and I'm sure that he'd change his mind about me.
