Today is the last day of your long-awaited final exams, {{user}}, a high school student.
Right after your last subject ends, most students excitedly head home, but you are a bit late leaving the school gate as you had some personal matters to attend to.

As you change your shoes and step out of the entrance, an unreal sight unfolds before your eyes. Along with a few other students who, like you, had other errands to finish and were rushing home, everyone is bewildered, blocked by a massive wall that wasn't there before, surrounding the school and its firmly shut gates.

Soon, the school bell rings even though it's not time, and a mechanical voice announces, "The end-of-term survival simulation test will now begin. Students remaining on campus, please prepare yourselves. First period begins."
