100 Hardest CR Questions on the Forum

Is there a reason that some of the questions are duplicates (eg. 86 & 98, 4 & 5, and 43 & 93)?

Thank you - I did not have time to clean this list; that's the main reason, but in reality it is just some questions do get discussed multiple times... esp the hard ones. That's mostly because users do not use the search function. I will clean it up - we have also found a few questions that need to be pulled off this list due to incorrect answers - thank you WaterFlowsUp!

BB- I can save you a little time regarding duplicates. I copied and pasted the list into excel, then sorted and the list by topic. It enabled me to see the duplicates easily since they were right next to each other. I found a couple more duplicates. Entire List included here:
1 & 77, 3 & 18, 4 & 5, 43 & 93, 46 & 61, 47 & 53, 75 & 81, 86 & 98. Funny - I noticed that since you have two independent samples from each of the duplicates the results are surprisingly similar (e.g 4 & 5, 47 & 53 and 75 & 81.

I must say that this list is very helpful to refine your skills as you improve and reach the upper level of CR. Kudos x 100.

On another note - I did a quick analysis of the results on the list and thought it may be useful in terms of what people struggle with. The top categories of the top 100 CR questions are as follows (list factors out duplicates and does not include unspecified categories:
Assumption - 24%
Weaken - 11%
Inference - 9%
Strengthen - 9%
Bold Face - 8%
Evaluate the Arg - 8%

Hope its useful.

Wow, Good list BB

Hope if possible doing it for SC as well

Thanks Avohden For you analysis of the repeat questions.


Kudos to you both..

GNPTH - you wish has come true

Here it's for SC https://gmatclub.com/forum/100-hardest-sc-questions-on-the-forum-162101.html

Friends ,

Thanks so much for liking the list. I can't emphasis further on how much I am thankful to BB for such an important list. To enhance the goodness , BB has come up with a new set of SC questions. Avohden , great job. Even I missed out that redundant part of the list. I would request users to solve those questions and provide us the feedback if anything is found debatable.

BB,

Welcome . I suppose it might be better if we can have "EXCEPT" tag to correctly specify. I found 1 question to be faulty, which needs to be removed off the list along with the redundant ones. We also need proper tagging on the source, this is because few sources are unpopular for coming up with the faulty questions and debatable OAs.
1 more request, can we have the list expanded to 200?

Thanking all for the support and coordination.

Thanks BB, excellent work!
Best.

Thank you for sharings. I must improve this section.

Are these Questions avaliable in Pdf format by any chance ?

The questions here seems to be pretty tough at least timing wise.
I just visited this thread after solving the hard section from GMATPrep but found the questions here way too difficult.

This thread is garbage. It's riddled with wrong OA's and poorly written, non-GMAC questions.

First of all, you could say the same concept more politely. Respecvting who does this job for the community.
Secondly, the questions are from several sources such as MGMAT and others..........

Thank you

Yes, I apologize for the harsh language. GMATClub is a immensely helpful tool for those studying for the test.

I will put it in politer terms: The moderators should look through this thread for wrong OA's and poorly written questions.

Look at this one for instance instead-of-blaming-an-automobile-accident-on-driver-error-137260.html

From MGMAT yet it adheres to the rules for posting a question on the board.

I do really think is a good question written by a well-established prep company.

There is nothing wrong in the compilation provided by the gmatclub

There are a few where the OA provided is questionable. I've been going through most and can't remember which ones exactly.

Again, I apologize for my harsh remarks.

Is there any overlap with GMATprep Tests?

Thanks
