I spoke to someone that has taken the LSAT and he told me to read the whole dictionary.
He said that it will help in seeing what relations the words have and will help me to answer questions better. What do you think? Is this worth my time for those of you who have taken the LSAT?
No. A far better use of your time, if you are looking for reading material, would be to read judicial decisions and critique them. Break down the argument sentence by sentence, and ask yourself how the author builds to and supports his or her main point. You can also do this with newspaper editorials, readings for school, and any texts that make an argument. Your critical reading skills will improve a lot.
Here's another one: Most of the hard words on the LSAT are simply words that appear all the time in major newspapers and books written for adults. Usually, when reading, if we come across a word we don't know, we just move along and try to pick up a rough approximation of the word's meaning from the context. What you should do is stop, find a dictionary (or just have it nearby while reading), and look up and memorize the word's meaning. You'll probably learn 75 new words this way between now and the time you take the LSAT, and probably three or four of them will be somewhere on the test itself.
