For Joy: GMAT, GRE & LSAT's Reading Joy, I believe you posted a message asking about the level of difficulty among these reading comprehension materials. Just by chance, I have tried all of them and have a little experience which I would like to share with you.
You must already know that they are all quite similar in terms of selection of topics, length of articles, range of vocabulary, and attitudes of writers. In fact, most teachers of any of the test will recommend their students to read materials from the other 2 tests. They prove to be very good supplementary materials. I would recommend the same.
With regards to the difficulty, they are really pretty close except that LSAT is a little longer, cover more subjects in social science. If you really want to get specific, I think GMAT is probably the most difficult, followed by LSAT, then by GRE.
Mr Yu Minghong always recommend us to read Times or News Week in order to improve our reading skills. Actually there is a better source of material that you can draw, that is, the Economist.
Do you know how to distinguish our test reading materials from other things that can be read? Our reading materials (whether for GRE, GMAT or LSAT) are from 1) text books for graduate study in the US; 2) supplementary materials that American professor ask their graduate students to read. In other words, these materials were written by INTELLECTUALS. Times and Newsweek both are commercial magazines. The language that is used is more like that for a newspaper. Get a copy of The Economist and compare it with News Week and Times, you will see the difference.
In America, believe it or not, an undergraduate degree will not really get you ready for the society. If you need serious learning, you need to go to a graduate school. For many reasons, I believe the top Chinese universities provide better under-graduate education than their American counterparts, even though I also believe that America's graduate schools are, in general, unquestionably the best around the world. That is why we both are working on the G's, isn't it?
Back to the tests, other parts (critical reasoning, sentence correction, etc.) of all those tests take their sentences, as well as the ideas carried by the sentences, from those similar reading materials. That is why I strongly disagree with Mr Guan Weidong, who tends to tell his students to be complete fools while taking logic tests. On the contrary, all logic questions carry ideas that are LOGIC in terms of common senses.
