I agree that speed reading probably isn't useful, but I would HIGHLY recommend that anyone who isn't very proficient in typing spend some time this summer working on typing skills. Many law schools give students the option of typing their exams, and you will have a huge advantage if you can type quickly and effortlessly. The more automatic your typing process is, the better you'll be able to focus on the content of what you are typing (whether you are taking notes in class, preparing for class, or taking an exam). If, on the other hand, you have to concentrate on your typing to type, it may interfere with your ability to take notes or stay focused during an exam -- you may be better of hand-writing.
On a related note, I recommend that you decide early on whether you will write or type your exams, and then use that same method to take notes and study. When I was studying for first semester exams, I actually practiced typing out my flashcards. It is a good idea in preparing for an exam to simulate as closely as possible the means by which you are going to demonstrate what you know. You will get a sense for whether things "look right" and "feel right".
