Query: Buy the actual tests

I don't see why people buy anything fromKaplan, Princeton Review, and Barron's etc.when they can purchase the actual tests.Each one of these "prep" tests are differentin some shape or form from the real test.Usually the questions are as not well thoughtout as in the actual tests. Many times theyare more complicated or less complicated than required.I can't think of one reason to buy their products.
