Time and Task management are one of the most important skills to learn in life and skills you can refine as you go. One of the things that has helped me is understanding when your most engaged and what time of the day you will learn the most. I took a lot of morning classes as thats when Im most focused. At nights I would work a part time job where I worked 25 hours a week. How you decide to send the time in between is completely up to you. I would advise using a Google calendar and any free time you have writing what are the top three things you need to get done that day. I didn't have a heavy workload as far as home-work is concerned. More large term papers and midterm and finals exams. Choose a location that works best for you to study in, I didn't have too much success studying at the library and prefed to study at home.
