What you can do
Find a study area. It should be free of distractions. Use a desk if possible. Don’t have the TV on.
Set priorities. Since your schooling is important, resolve that you will do your homework first.
Don’t procrastinate. Have a definite schedule for your homework, and stick to it.
Have a plan. Decide which project you should tackle first, which one second, and so forth. List these on paper, and give each one a time limit. Cross off each assignment as you complete it.
Take breaks. If you find yourself losing focus, stop for a brief rest. But get back to your homework as soon as possible.
Have confidence in yourself. Remember, the difference between a good student and a poor one usually has more to do with diligence than intelligence. (Proverbs 10:4) You can make a success of school. Put forth the effort, and you will reap the rewards.
