Yesterday I received my copy of the new GMAT Official Guide 13th Edition, which I had preordered. The book was originally listed as shipping in early April, so they moved the shipping schedule up by a week. I’ve spent a couple hours looking through the book and comparing it to the previous OG 12th Edition. Here’s my synopsis.
1. I scanned through the Quant section and tried to estimate the number of new questions. For Problem Solving section I counted 66 new questions out of 230; for Data Sufficiency it was 44 new questions out of 174. Overall, that’s 110 new Quant questions, which is about 27% of the total. I didn’t look at the Verbal too closely, but I’d imagine the percentage of new questions is about the same. Keep in mind I estimated these numbers (Edit: I’ve read elsewhere that’s there a total of 156 new questions out of 907 for the whole book, so my numbers for Quant might be too high).
2. The overall difficulty of the questions doesn’t appear to have changed. I didn’t see any new Combinatorics or Probability questions in the Quant section. Thus, the chief complaint with the Official Guide remains the same – it doesn’t provide enough practice with 700+ level questions.
3. For Integrated Reasoning, there’s a 10-page brief synopsis that introduces the 4 different question types, but no examples within the book itself. Instead, for practice IR questions, you have to visit the publisher’s website and register with a unique code that’s found in the back of the book. Once you register and create a login, you have access for 6 months. On the website, there are a total of 50 example questions; however, each question can have multiple sub-questions, as per the screenshot below:
4. Amazingly, the Integrated Reasoning sample questions allow you to use an on-screen calculator. This should help save some time on this section. I don’t think the calculator will be available in the regular math/ verbal section.
5. The Diagnostic Test at the beginning of the Official Guide hasn’t changed since the last edition
6. In the Analytical Writing section, the Analysis Of An Argument question is still in; the Analysis Of An Issue question has been removed.
That’s my first impression of the book; it’s available for order on Amazon here.
