The 2015-2016 school year is split up into four periods: Sept-Oct; Nov-Dec; Jan-March; April-June. At the end of each, the students have a week of exams covering all they learned during that period. Last week they had their first period exams.
In each class, a teacher surveys to make sure that there is no cheating on the exams.
Phew! I’m sure they’re glad that’s over.
