    Developing good study habits isn't easy.____ In this way, you'll become more and more successful as a student.
    Start by allowing no interruptions____You have to give 100 percent of your attention to your work. Don't allow yourself to be distracted by friends or fellow students. Keep your goal in mind; know what you have to do and when it needs to be done. Don't let other people influence you into not doing your work.
    ____If you study best in the morning, plan to do your hardest subjects first. Remember not to leave today's work till tomorrow. A delay like this is called procrastination.
