I would need a description of a school year in Japan, not too detailed, just a few important dates - like holidays and exams -, and details about when the new school year starts and when the year ends for middle school senior students and general details about a senior's school year (e.g.: are the seniors' exams at the same time as those of the other students? Does it depend on the high school they chose when their year ends and when their exams are?)
Thanks so much in advance for any help - it'd be really, really appreciated!
