Hi Bunuel ,

Thanks for the sharing the list of questions.

Do we anywhere have the option to download all the questions in one go or we have to access them separately only.

Thanks!

The list is regularly updated so there is no downloadable file.

Hi bb

Is there any way for a user to search questions by the level of difficulty (e.g. 85% above) in this forum? I know the difficulty level is generated by an unofficial algorithm, but I feel that the computed level is pretty much reliable indicator.

There are 3 difficulties that are available for search. That’s how the system works - hard, medium, and easy.

So the questions labeled "hard" are questions you need to get right on the exam regularly to score a 700?

Is it still possible to hit a 700+ while acing easy and medium problems and then getting about half the difficult ones correct?

i've been studying for a month or so - I still haven't taken a practice exam to gauge where i am (i know i should), but just wondering for a quick check on my status. Ive been doing so-so on the medium/hard problems - getting the mediums usually correct, but the hard ones occasionally..

Hi and welcome to GMAT Club!

A test is really the best indicator since there are many elements involved and it is no substitute to understanding your score. Though it is also good to be able to know on a daily basis how you are doing and not waiting a week or a month to take a test.

It is tough to tell based on the pure number of questions without knowing the difficulty or which ones you missed so here is what I would say based on my crazy method (completely unscientific):
if you can take 10 questions of easy, medium, and hard difficulty, and....

miss 10%, you are at 750.
miss 20%, you are at 700
miss 30%, you are at 650
miss 40%, you are at 600

Now, I would recommend that you actually study using a guidebook or a course (something other than OG).
Also, I want to warn you that some of the OG 12 questions are in the GMAT Prep so you don't want to head to the OG 12 (or perhaps that's OG 21 you meant to say?).

And if you want to see how wildly scoring differs based on a few factors, here is a topic for you:
