Hey,
is it public information whether partially correctly answered questions yield any score?
When I take MGMAT CATs I score in a devastating 3-5 range (< 30 percentile).
I answer most of the questions correctly, however sometimes I miss one question in a challenge that consists of several questions.
I wonder if MGMATs IR scale is representative as I usually score in the 90+ percentile on Quant/Verb.
I don't really have much of a problem with the individual questions, either. However, I feel like the timing is way harder than on the Quant/Verb parts.. especially the table analysis always consumes about 4-5 minutes.
I should have just taken the GMAT before the test change...

For a given problem, you must get all of the individual answers correct to receive credit.

IR doesn't only consist of multiple choice questions.Deanrobbins1 wrote:How could you possibly get questions "partially" right on a multiple choice test?
However, there are several problems that consist of several questions... so you can miss some questions while answering others correctly.
Just look at a few examples and you'll understand.

Kevin,
(And yeah, dude, I'm totally kicking myself for not being on top of this before the change. I totally empathize with you. Something tells me, though, that we'll both do great.) Good luck!!!

I definitely agree with you. This stuff is really tough. Check out Stacey Koprince's article on GMAC's release of IR percentiles. https://www.beatthegmat.com/mba/2012/06 ... he-scoring. The good news is, as with AWA, we won't need great scores, just good enough scores. Apparently that means in the 4-5 range. So only about 50% accuracy.When I take MGMAT CATs I score in a devastating 3-5 range (< 30 percentile)...

I kind of liked IR, when I first glanced over it. So I thought it wouldn't be too bad to invest a bit more time in a sophisticated preparation. Looks like I was wrongmeanjonathan wrote:Kevin,

I'm hoping the MGMAT Percentile calculation is totally off and it won't be too bad when I take the actual exam...

On dichotomous choice IR questions, which are three yes/no or true/false question in a single table, you must get all three correct to get any credit.
This may seem harsh, but it's actually fair--this is a good opportunity to practice some GMAT math!
Since there are two choices each for three questions, there are 2^3=8 possible combinations of right answers. That means a stone-cold guess will be right 1/8 times--that's a little less than half as often as guessing on the quantitive or verbal section.
However, there are 3C2 = 3!/(2!1!) = 3 ways to pick two correct answers and get the third wrong. If partial credit were awarded for partial answers, then there would be 3 + 1 = 4 credited answers out of 8. So, you'd have a 4/8 = 50% chance of getting points on a random guess! This is way too high, and so of course, the testmaker can't credit partial responses.
