How It Works
How to Plan Your Semester Schedule
A semester planner accounts for all your time commitments.
Formula
Total Committed = Class + Study + Work + Personal
Free Hours = 168 (hours/week) - Committed - 56 (8 hrs sleep x 7)
Experts recommend keeping total commitments under 60 hours/week for a healthy balance.
Worked Example
15 class hours, 30 study hours, 15 work hours, 10 personal hours.
- 01Total committed = 15 + 30 + 15 + 10 = 70 hours
- 02Free hours = 168 - 70 - 56 (sleep) = 42 hours
- 03Daily commitment = 70 / 7 = 10 hours/day
Frequently Asked Questions
How many hours should I commit per week?
Aim for 45-60 hours total (class + study + work). Above 65 hours, burnout risk increases significantly.
How many hours should I sleep?
The calculation assumes 8 hours/night (56/week). Reducing sleep to study more actually harms academic performance.
Can I work full-time and go to school full-time?
It is extremely challenging. Full-time work (40 hrs) + full-time school (45 hrs) = 85 hours/week, leaving very little free time.
