In one sentence, describe what the following article is about:

You can make a single timetable that will stay the same each week. Or, you can build a custom one for each week, that changes depending on the specifics of that week. You would build all of your custom timetables at the same time.  For a custom weekly timetable, start in reverse. Start with big assignments or final exams and work backwards. Your study schedule will need to change depending on what big assignments are coming up.  Don’t forget to fill in everything you brainstormed earlier in the process. You should do this before you put in study times. This includes all regular commitments like a sport practice. You need to do this first so you know where you can put your study times. If you’re making a custom weekly timetable, don’t forget to include exceptions like birthdays and holidays. Aim for blocks of study time that are fairly long, such as 2–4 hours at a time. This will help you get into the groove of studying and help you to be more productive with your time.  Just because you don’t have a large chunk of time doesn’t mean you can’t schedule a study period, however. If you feel it will be beneficial to schedule in 45 minutes here or an hour there, by all means, do so. You’re going to want to schedule more time for more difficult classes. Break are essential to your success. You’re not a robot, so you can’t work non-stop for hours on end. You’ll do better overall if you give yourself regular breaks from the work. Many experts recommend that you work for 45 minutes every hour, and then break for 15 minutes. Everyone is different, though, so experiment to find what works best for you. Remember how you gathered all your of assignments and syllabi? Now is the time to put them to use. You can schedule blocks of time for particular classes and also write in assignments and give yourself chunks of time to work on those.  Things will change over time, of course, and something you planned for two months ago may not apply anymore. But don’t let that stop you. Look at this as a helpful guide, something to keep you on track and something that will help you break large assignments into small pieces. If you always have a certain amount of homework for a class every week, that would be great to add to your timetable. For example, if you always have 20 math problems to do each week, you can break this up in your timetable. Working on different subjects during a single session will keep you from getting completely burned out by one subject and having no energy to do anything else. Of course, this can change come exam time when you need to devote all your energy to a single subject! Color coding classes and responsibilities will help make your timetable easier to use and easier on the eyes. You might be looking at this timetable a lot—make it your own! You might want to use colored pencils if it’s on paper. Or you could highlight things on the computer and print in color. If you’re using an online-only app, the timetable will already be color-coded, though you may be able to customize it to some extent.

Summary:
Choose a single or custom timetable. Block your study times. Schedule time for breaks. Be as specific as possible. Schedule multiple subjects during each session. Make your timetable look nice.
