Chapter 50

Time for the End of the Semester (期末の時間, Kimatsu no jikan) is chapter 50 of the Assassination Classroom manga.

Short summary
It's time for the end of the semester. Everyone are doing their best to work hard because whoever reaches the 1st place in any of the 5 subjects will be given a chance to shoot down one of Korosensei's tentacles.

However, that would not be so easy because the top 5 students of A class will be their most formidable opponents.
