Hi, I wonder whether past tests (especially all tests after the shift from old to new GRE) are available in paper form? I heard there are 4 real tests in the market, but is that all? I think using the real test is the best, but if there are only 4, I'm afraid of consuming all of them before I'm ready to take full-timed test. I'm thinking to read some prep books and then take the real tests...is this a good way to prepare for GRE? Or should I only use practice tests (not real ones) and save real one for timed test? In that case, which company's practice tests would be the best? Thank you in advance.
