The GMAT Club Guide to The GMAT Official Guide 2020th Ed
Error Log & Difficulty


The Official Guide 2020 is a great resource - it has real GMAT questions, all questions are arranged in order of difficulty, good explanations, etc but it has one major flaw - no way to sample specific questions or ability to target a specific area - for example all SC questions with idioms or all DS questions that deal with geometry. This Guide attempts to correct that flaw (and a little bit more), making Official Guide even better.


!
Google Spreadsheets Version is here: https://docs.google.com/spreadsheets/d/ ... sp=sharing

There is no Excel Version this year :)



Use this guide to:

  • Find Difficulty about every question available in the-Official Guide for GMAT Review
  • Help find specific practice questions and build your custom practice tests that focus on your weak areas
  • Keep your OG Practice in one place with an Error Log and Analytics
  • Understand difficulty of each question (it is not very linear as you will notice). We have split difficulty into 4 groups (easy, medium, hard, and very hard). This split is based on the percentile of the question difficulty as determined by GMAT Club Timer sessions
  • Explanations are linked to each question for easy reference
  • Updated the Error Log numbering
  • The split of hard/medium/easy questions has somewhat changed and in part that's true for new questions that have been added as well as existing questions being "harder" due to members making more mistakes - so the changes are happening on both ends of the equation if that makes sense.

PS. If you find any issues with the file, please post here or PM me. It's a late night and I have completely reworked the Error Log as well as the Stats module so it is possible something may need tweaking

There is numbering error in the error log. In the transition from the RC section to the CR section, cell D612 looks at non-existing values in sheet RC. This causes a chain of incorrect lookup values for the questions numbers. What's the process of updating the google spread sheet?

Thank you - indeed. There was an extra RC line. I have fixed that. Thanks for pointing it out!

Here is the link to
OG 2020 Quant Error Log: https://docs.google.com/spreadsheets/d/ ... sp=sharing

I don't think we have the Verbal Error Log yet.

Hello,

first of all, thanks for the effort in producing the error logs, they are the most useful tool to track the progress in GMAT preparation.

I have a question regarding the OG2020 Error Log: when the links to the GMATClub explanation of the answers will be made available, like it is done for OG2019 Error Log?

Thanks!

Hello bb, any updates on when an error log for verbal 2020 could come out? I just purchased the verbal OG 2020 and an error log would be very helpful. thank you!
