Exam window scheduling for cohorts is a start, an end, and who is in the sitting. OnlineTestPlus can hold that window. AmroMeet is a meeting link. Do not book an exam as a chat slot.
Late joins and extra time belong in the same policy as the paper. The window does not invent fairness.
Practice windows on Academy are drills. They do not issue this credential.
Configure the exam system, then book a consultation if several campuses share one sitting.
