I am writing in connection with the IR section. I am struggling with it especially that 30 minutes are not enough to do the huge work that this section requires.
Therefore, i am wondering whether my strategy to focus on the first 7 or 8 questions and to guess randomly the remaining question could work? This section is not adaptative, right? I am aiming to have 7 or 8. 6, even 5, is fine for me.
I will be glad to read any input and/or experience with this respect. Many thanks in advance.
I'm happy to help.
First of all, yes, the IR section NOT adaptive. The computer dreams up a batch of 12 questions and just assigns them to you all at once --- how you do on each has zero effect on the next one you see.
Also keep in mind --- of the 12 questions, eight will count, and four are experimental. But here's the catch --- we have no way of knowing which four
are experimental. It could be the last four, or it could be the first four, or scattered anywhere through. (There are actually 12C4 = 495 ways for four experimental questions to be randomly scattered among a group of 12.) This creates problems for your proposed strategy. Suppose, for example, on your particular IR section, the first four questions happened to be experimental --- then, if you did, say 7 questions with true effort, only three of those would be questions that count for credit. That's a problem!
Unfortunately, the way they have set things up, you really have to make an effort to get through all 12 questions.
Here's what I'll suggest. First, here's a free ebook on the IR section. http://magoosh.com/gmat/2012/gmat-integ ... ing-ebook/
BTW, here's a blog about the IR calculator:http://magoosh.com/gmat/2012/the-integr ... alculator/

Does all this make sense?
