Airport pickup and dormitory (AZON condo) check-in are usually conducted on Sundays. There is no special schedule on Sunday. You can eat in the cafeteria, use the study room, or go out.
If you have any questions about how to go out or other questions, you can ask the office staff. (PHILINTER operates on-duty staff on Saturdays and Sundays)
On Monday, there is a level test, orientation, purchase of necessities for daily life, and currency exchange.
Regular classes start on Tuesday morning. You can pick up your class schedule at the office at 8:00 am on Tuesdays. If your study period is 1 or 2 weeks, regular classes start on Monday afternoon.
