I think you are much more likely to learn and deeply ingrain the right answer if you explain why the credited response is the right answer yourself. If you just read someone else's explanation about why an answer is right it will just go in one ear and out the other and on your next test you likely won't apply the explanation given for similiar problems. However, if sit down and try to figure out for yourself why the credited response is actually the right answer and try to think creatively about why it is so, you're much more likely apply what you learn to future tests. And remember, if you really can't figure one out, you can post your question to this board and people will respond.
Also, i would really recommend purchasing from the LSAC their preptests where they give the official LSAC explanations to the exam. They already have one such preptest available and another coming out in April.
Sorry - didn't answer your initial question. but just thought you might like to try this technique. It has been quite effective for me. 10+ point improvement on my score before even starting my Princeton Review course.
