1. Add Fixed Commitments First
Mark classes, travel, meals, sleep and existing commitments. This prevents you from planning with time you do not actually have.
2. Choose Weekly Outcomes
Select a small number of meaningful outcomes for the week. Break each into tasks that fit individual study blocks.
3. Leave Catch-up Space
Keep at least one flexible block. If the week goes as planned, use it for revision or rest rather than filling it automatically.
