Assassination Classroom

The Assassination Classroom watch order runs across two seasons and 47 episodes, plus the Jump Super Anime Tour Special and Meeting Time OVAs. Begin with the 22 episodes of the first season, then continue straight into the 25-episode second season, which completes the main story. Save the two OVAs for the end: the Jump Super Anime Tour Special and the Meeting Time OVA both work as extras rather than essential plot, so they slot in cleanly after the finale. Anyone looking for the correct order can simply follow the two seasons back to back and treat the OVAs as bonus viewing. That keeps the classroom's assassination arc intact from the first episode through the last, with no gaps or detours in the chronological sequence to trip you up along the way.
