After spending much of this past weekend trying the new GMATPrep, I have better insights on the new IR section. Here is what I found:

• There are 12 questions and 10 prompts in the IR section
• There is a timing recommendation of 2:30 per question that is pretty reasonable, although you will need more time to read some prompts than to read others
• Scoring is 1 to 8, with no halfbased primarily on the number right, with no partial credit, although there seems to be some forgiveness at the top, because 0,1, 2, or 3 wrong led to a score of 8

There are also a number of significant changes to the test that aren’t specific to the IR section. Here is my summary, including my takes, on the changes:

We invite you to test your GMAT knowledge for a chance to win! Each week, we will post a new Challenge Problem for you to attempt. If you submit the correct answer, you will be entered into that week’s drawing for a free Manhattan GMAT Prep item. Tell your friends to get out their scrap paper and start solving!
Here is this week’s problem:

The expression x#y denotes the product of the consecutive multiples of 3 between x and y, inclusive. What is the sum of the exponents in the prime factorization of 21#42?

Editor’s Note: This is a follow-up to Liz’s post from Wednesday, reviewing the new GMATPrep 2.0.

Late yesterday afternoon I got an exciting email from GMAC! It said that GMAC had found and fixed what was described as a section scoring error and posted an updated version of the GMATPrep practice software for students to download.

Of course I immediately downloaded the new software in order to test it. Version 2.1 asks if you want to replace version 2.0 before it downloads, which is a nice feature, but a bit irrelevant, because of course you want the version where IR scoring works.

The big surprise is that the IR section score is on a 1-8 scale, not 1-25 as it appeared to be previously. I tried it and missed one question in one out of 12 prompts and got an 8, but when I tried it again and missed 1 question in each of 4 different multiple answer prompts, I got a 7, so it looks as though GMAC must be giving some sort of partial credit, but I won’t be positive of this until I’ve tried the test several more times. Unfortunately, you can’t complete just the IR section and get a score. You have to complete the entire test if you want scores.

After you finish the test, you can use the review screen, but beware, as soon as you exit, you will no longer have access to the questions that you answered. The software will save your scores for you though, so at least you don’t lose those.

Editor’s Note: This is Part 2 of our new blogger Andrea Pawliczek‘s first post. You can read Part 1 here.

Let’s take an example of a critical reasoning argument that might appear on the GMAT.

Plainsboro Hospital completed a study that revealed that the majority of post-operative bacterial infections are caused by catheters. In order to reduce post-operative infections, Plainsboro Hospital decided to implement new sterilization procedures to kill bacterial on catheters before they are inserted into post-operative patients.

Real World Analysis

Take a minute to brainstorm some of the questions you might ask if you were a manager at Plainsboro hospital evaluating the proposal to implement this plan.

This morning I was delighted to discover a new version of GMATPrep up on the mba.com website. You have to have an mba.com account and be logged in to download it, just as before, but Mac users will be pleased because now there is a version that runs on the Mac OS (version 10.6 or greater) along with the version that runs on Windows XP, Vista, or 7.

After I downloaded and started the actual test (there are two provided, just as with the old GMATPrep) I noticed that it looks more like an actual GMAT administered at a test center than the old GMATPrep looks. It has all of the instructions and the mini-tutorials that the real test has. Read more

Editor’s Note: We’re pleased to introduce Manhattan GMAT instructor Andrea Pawliczek as a writer on our blog (even though she is a New England Patriots fan)! This is Part 1 of her two-part first post. Give Andrea a warm welcome in the comments!

Success on the GMAT demands many efforts: learning new skills, sharpening existing skills, and in some cases forgetting or setting aside some of the skills that we use in real-life. It is this last demand that often proves the most challenging, as a GMAT test taker must veer away from the type of thinking that has served her well to this point in life.

One such case occurs in data sufficiency problems, which ask us not to solve a problem but rather to identify when we have enough information to solve a problem. In both my professional and personal life I have been asked to solve problems on many occasions (How much will the new project cost? How many gallons of paint do I need to buy to paint the living room?). I cannot think of a real life occasion when I have specifically been asked when I have enough data to answer a question.

Former Manhattan GMAT President Andrew Yang was featured in full-page article in Time Magazine about Andrew’s new endeavor, Venture for America! Added bonus: Manhattan GMAT gets a shout out in the first paragraph!

Below is a screen shot of the post. You can read the whole article over on Venture for America’s site.

Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! Check out our upcoming courses here.

This is a repost of a blog post from August of 2009 that was originally written by our then CEO,  Andrew Yang. We frequently get questions from students about score guarantees so we felt like it would be useful to share our opinion of these guarantees, and why we don’t believe in them, again. The original post can be found here.

We occasionally get questions about why we don’t offer a score improvement guarantee.

There are a few little reasons, and one big reason. In our experience, a test prep score guarantee has a number of attendant issues: Read more

The launch of the Integrated Reasoning (IR) section is getting close! The last administration of the old version of the GMAT will be on 2 June; the next-generation GMAT will launch on 5 June. It’s not too late to study for the old version, but it’s also not too early to start thinking about studying for the next-gen test, including IR.

So let’s talk about one of the four IR question categories: Graphics Interpretation. IR in general is a mix of quant and logical reasoning, so expect to bring your critical reasoning and reading comp skills into play on this section.

Before we dive in, just a note: a new Official Guide (13th edition!) was just published; it has an IR section along with an additional IR resource online (to which you get access if you buy the book). I would guess that most test prep companies will also be releasing their IR study materials next month (we certainly are!).
