Found this brilliant question on Data sufficiency, do give it a shot. I was completely stumped.

That's a GMAT Club Tests question. Glad you liked it.

Hello Team, Good Morning Good Evening!
@bb any ways you can find the reason for this ?
Any backend logs that you take manually to identify why this got happened?
My initial observation and hunch is the first question values more than other question is this correct in backend algo? I heard everywhere its just a myth but wanted to confirm if that is the case. Thanks for all your help & support to understand this dynamic unpredictable points algo.

Hi. There is an issue with question selection for those who perform in mid-tier. Algorithm has been hoarding hard questions and not giving them to people, but we have an update coming that should fix this tomorrow night.

PS. On the focus edition the first questions are much less important. It’s almost not visible

Do you mean to say that the impact of getting the first question wrong is subtle, and not too much

Because I’ve heard people mentioning frequently that an incorrect answers in the first few questions impact a lot

Yes. The impact is much more uniform it seems based on my experiments with GMAT prep official exams

With old algorithm, do you mean classic? or has the algorithm changed for FE recently?

That was the GMAT classic algorithm in 2023.

The gym at focus edition has a slightly different algorithm and approach. The first few questions are not overly impactful

Here when the last 6 questions were attempted incorrectly, it resulted in a higher drop compared to the other two scenarios. Is this a pattern observed in FE as well? Because i think a lot of test takers who might be struggling with timing would end up having higher number of mistakes in the last few questions...
