An important step in managing your course load happens very early, typically at the very beginning. This is usually when the course outline will be handed out and explained, and it often tells you how you are going to be assessed. This will let you determine how much time you will need to spend studying, writing papers, and so on. You should think about this carefully to decide how much time you will have left for other activities: other classes, hobbies, or work. If you take on too much, it will before impossible to do well. Sometimes you can do courses at later times, and this can help you balance your work. Other times you may simply have to set priorities and do less overall. The main idea is that if you take on too much work, you may fail at all of it: successful management means only doing the amount of work you can do successfully.
