Establishing habits of study is extremely important. Knowing when and where you are going to study saves alot of time in making decisions about studying. Locate a place which is comfortable for you and has few distractions, such as friends, noise, etc. Identify periods of maximum alertness.
Some people are more efficient in the mornings and others in the evenings or late at night.
Find out when you are really effective and plan to do your studying then, if it is possible. Limit study time to no more than two hours on any one course at any given time. After l.5 to 2 hours of study, you begin to tire rapidly and your ability to concentrate decreases rapidly. Taking a short 10 minute break and then switching to some other course will provide enough change to keep up your efficiency. Set specific goals for each study unit.
