How to make a study timetable
Make a list of your responsibilities.
You need to think about and write down all of your responsibilities so that they can properly be factored into the list. By thinking about all of this in advance, before filling in your timetable, you'll make the actual creation of your timetable go more smoothly.
You should consider all of your classes, your job, your chores, sports and exercise, and anything else you do on a regular basis during the times you might be studying. Don't forget people's birthdays and major holidays.
