Avoid study overload, exhaustion and last-minute chaos by creating a schedule using a spreadsheet for everything during the semester: studying, classes, laundry, socializing, grocery shopping, exercise and sleep. Flexibility needs to be a part of this schedule, too. For the study schedule, you can make each credit hour equal to two study hours. For example, if your biology class is four credits, plan eight hours during the week to study.
You can print several copies of the schedule and put them in places where they are easily seen and not forgotten, such as one on the refrigerator, one in the planner and a small one in your wallet. Creating a habit of organization for classes is tough at first but once you become accustomed to the routine, it is easier to stay on track. Know what the final goals are and why they are significant.
Learning how to say "No" is key to avoiding distractions, according to the Bureau of Study Council at Harvard University. They also recommend that "If you find yourself consistently loosing concentration, notice internal and external factors that might be affecting this." Knowing your weaknesses for distraction is the beginning to finding your strength to overcome it.
Some projects need double the normal time allotted for study; plan in advance for these types of projects. Take 10 to 15 minutes each day to modify the schedule or to look in advance to what is in the near future. Cornell University's Center for Learning and Teaching recommends using odd hours such as one or two hours between class to study, and not to study more than two hours for one subject.
