In Japan, the school year was very unique. Classes started in April and ended in March, and were divided into three semesters. The first one began the first week of April, until mid- July where students had their end of term exams right before the summer vacation. Classes resumed in September until December before the winter break. The third and last semester opened on the second week of January until the end of the term in March.
Technically, Ara had missed the term end exam last December, because she was in a coma. But she already took the special exam at the hospital, and her results still topped, so her class rank didn't change.
Now, it's the second week of the last term, and graduating students were busy with their exams. By this time, they already knew where they would be studying after graduation. But, before the grueling days of examinations, there's an activity that most students look forward to: the four-day school trip.
