The key for me to studying is to find a topic that I find interesting. ADD or not, I think most people have a hard time sticking with something for long periods of time that they are not interested in. If it's a course that you are required to take, find ways to help yourself make it less boring. Try highlighting in different colored highlighters or taking notes with different colored pens. Have you tried two-column note taking? It's a great method that forces you to flip the information into a question/answer format and think about the information differently. Google it. Make flashcards. Make up songs to remember the information. Come up with mnemonic devices. Try studying in different places for a change of scenery. Take your materials outside for fresh air. The possibilities are endless.
