Remove all forms of external distractions including phones and instant messaging on your computer. Have someone else set up a password on your computer so that you cannot log on even if you want to. Hand over your cell phones to someone you trust. Ask your family or roommates not to disturb you and to use low volume or headphones when listening to music or watching TV nearby.
Study in a room that is well lit and a comfortable temperature. Avoid noisy high-traffic areas such as your family living room or dorm common room. Choose a quiet corner in a library or another room similarly suitable for studying. Sit on a chair with a straight back. Avoid studying on your bed as you might be inclined to take a nap.
Bring everything that you require when you start studying, including all text books, study notes, pens, highlighters, calculators and a bottle filled with water.
Study when you're most alert. Know whether you are able to study well early of the morning, staying up late or after meals. Avoid energy drinks or pills.
Study for 50 to 60 minutes and then take a break for five to ten minutes. Have a healthy snack or a juice drink when taking your break.
Set up a timetable and stick to it. Draw up a schedule for all the subjects you have to study. Alternate between subjects so that you will not get bored. Study subjects that you find difficult or boring when you are most alert so that you will not be inclined to skip studying it or go to sleep. If you have only have one subject to study, work on it for the first half of your schedule and test yourself the second half. Provide sufficient time for meals and exercise.
