"Fast Times" is probably the best. However, it is not the most memorable for me. Although "Uncle Buck" is not strictly speaking a teen movie, Uncle Buck's tenderness and protectiveness surprised me. Once because of idiotic scheduling, my fourth period Bozo English class was several days ahead of the others, so when yet another extra-long fourth period was announced, I declared a movie day. A boy not known for good work or good behavior volunteered to bring in the film, saying it was his favorite. I took a chance, not knowing anything about the film, and was impressed that he would relate strongly to such a character. He never misbehaved again, and his work improved.
