The GMAT Club Guide to The GMAT Official Guide 2020th Ed Error Log & Difficulty https://gmatclub.com/forum/download/file.php?id=47716 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.

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

This is wonderful. Thank you so much for sharing.

Trying to find OG error log for a long time and finally found it here. Thanks for sharing! Any update on OG 2021?

Hi, Is there a similar Error Log/Spreadsheet for OG 2020 Verbal and Quant Review? Appreciate your help. Thank you

Hello all, thank you very much for providing this error log! I'm currently using it to work through the OG2020. I noticed that the OA of CR03940 (question 630) is set to "A" although the book states "B" as the answer. Just in case someone wants to update this. Thanks again! Leonie

Hi Leonie, yes I think the answer should be B This confusion might occur because the answer A was referring to this question, which has the same passage but different question. Our OG2020 version uses this instead P.S. you can update it in the document's CR sheet

Yes. It is pointed out a few posts above. Look it up. PS. Learn how to fish 😉 Posted from my mobile device

Thank you. I have updated the original error log. I believe Google updates it automatically if you have copied the spreadsheet (not if you downloaded it as Excel). Thanks! BB.

Is the OG Verbal review error log available?

2020 Quant review - The Error Log tab had only 300 questions rather than 319. This was because of errors in many lines. Corrected file is attached.

Hi! This is a fantastic resource. I have a question though, in what format should I input the time taken for each question?
