A useful schedule starts with the week you really have, not an ideal week with endless free time.
Add fixed commitments first
Place classes, work, travel, meals, and sleep on the calendar. The space left is your genuine planning time.
Match work to your energy
Put demanding problems or writing into periods when you usually concentrate well. Save lighter review and organization for lower-energy windows.
Leave breathing room
Plan roughly three quarters of your available time. A flexible schedule that survives an unexpected task is better than a perfect one you abandon.
