Try ot take care of all of your other business before you start studying. If someone interrupts you while studying tell them you are studying and hang up the phone. Study with a friend or do this over the phone. Make it more fun. Try to be interested in the subject. Somebody wrote the book for a reason. Try to fighre out why they wrote the book.

Chamber music via headphones; especially for math homework. 4 hours straight is the longest time spent studying.

Everyone has a different method. This is what works for me. First I try to eat well and excercise. Then I break things down into more manageable bits that will allow me to better focus on what I need to know. Ask yourself questions about the material. What is it that it is trying to tell you? Is this an incidental question designed to lead you to the real question? What is the intention of the question? Do any of the answers to those questions relate or validate answers that you already know regarding this subject?
