Each MIR class consists of three hours per session, generally held on weekends (Saturday–Sunday), either in the morning (9:00 a.m.–12:00 p.m.) or afternoon (1:00–4:00 p.m.). A short 15-minute break is provided midway through each class.
In the event of scheduling conflicts, public holidays, or special academic needs, instructors may request or be required to reschedule sessions on alternative weekends or weekday evenings. Classes may be conducted onsite or online as appropriate, subject to program approval and advance student notification. When necessary, makeup sessions may also be organized in intensive formats to ensure full coverage of course requirements.
