Learning some time-management skills can help you balance academic, work, and personal demands, all of which compete for your time. • The syllabus for a course can be a valuable time-management tool. It typically provides you with quiz and test dates and assignments and their due dates. Read your syllabus carefully and highlight important due dates. Then use backward planning by marking a calendar with each due date and the tasks you need to complete to meet each due date. Be sure to include other responsibilities, such as your work schedule, on your calendar. • To-do lists can also be valuable time-management tools. They are quick and easy to make, and you can easily update or change them. You can make a to-do list to cover the tasks for the day or for a week. You can include academic work or all your tasks. Pay attention to tasks that stay on your to-do list. These may indicate procrastination. Some tips for dealing with procrastination are given in the Chapter 4 Summary. • Use an ABC grid to prioritize tasks. Category A includes tasks that must be completed in 24 hours. Category B includes tasks that can be completed in a day or two. Category C includes tasks that can be put off for several days.
