This edition is published on June 5, 2012, and I ordered it on the same day because I attended the Kaplan Free GRE Practice Test that afternoon and the speaker announced this new edition. So I purchased it for $20 with Amazon Prime because I want the access for the MSTs and verbal practice test.
***It arrived today and I figure something relatively interesting.
1. This 2013 Premier has no difference whatsoever comparing to 2011-2012 Premier Edition. The table of contents and pages are exactly the same. For instance, if I flip to P.248 in 2011-2012 Premier, it is chapter 13 talking about the kaplan method for data interpretation; and if I flip to the same page in 2013 Premier, SAME! I tried several pages as well and they are all the same.
2. After flipping to the 1st page from the book cover, I figured out that I dont really need to buy this book because all you need is a online book link, a keyword and a kaplan online account. If you have 2011-2012 Premier, just use the same keyword and you will have free access to all features in the 2013 Premier "AND" GRE Strategies, Practice and Review 2013, including the MST.
3. Good thing it cost $20 to own for a 575 pages book unlike those college student rip off textbooks or course readers that cost over $100 - $200 that you don't even know if you will be flipping them at all. I know I purchased $120 hardcover textbook that the professor does not require us to know anything about it because the exam is directly from the lecture notes and worksheet. The textbook itself is just supplemental for your reference.
4. I dont think it is worth it signing up for those on-site classes for $600 just for GRE, even the just the Verbal (4 classes) by itself will not help too much. It really depends on the time you spend on memorizing the vocab and analyzing the questions for verbal. Quantitative reasoning just requires careful calculation, interpretation and experience using the "what if" idea on the comparison. For AW, that you need to have your own database or training in order to score high.
I think most grad school will accept the new GRE above 300, but should aim for at least AW 4.5-5.0 , V160, Q160 to be on the safe side.
