Leave one of the weekend days free for errands, fun and relaxation. Schedule time for fun, but make sure to schedule study hours before fun activities. If you schedule fun activities before study periods, it's doubtful that you'll ever get around to studying. Furthermore, it's hard to have a good time if you're feeling guilty about not studying. Schedule time for exercise and plan for adequate amount of sleep.
Regular exercise can alleviate stress and enhance concentration.
Too little sleep contributes to fatigue, a lack of mental alertness, and irritability. Maintain the ideal amount of sleep, especially when you're under pressure or busy with work. Leave a little room for unexpected events. If you pack your weekly schedule with too many details, the chances of your following such a schedule are very slim.
