Error Log for GMAT Official Guide 2020

Question

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.

Hi,

Is there a similar error log for Quant OG and Verbal OG 2020th version?

sowmitranalla · Answer

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?

Hungryman1 · Answer

The log's ID are completely wrong in the PS section

bb · Answer

Thanks. I believe these have been fixed thanks to  alexbern

bb · Answer

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!

ImadElKadi · Answer

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!

M1ke · Answer

I believe question 414 has the incorrect answer listed as correct. The correct answer is C, the incorrect answer is B.

Question it refers to in the spreadsheet - Easy 5% 
n, 15, 12, 9, 20
What is the value of n in the list above?

(1) n> 12
(2) The median of the numbers in the list is 13.

Correct answer B

Question actually in the book - Medium 25% 
k, n, 12, 6, 17 
What is the value of n in the list above?

(1) k < n 
(2) The median of the numbers in the list is 10.

Correct answer C

bb · Answer

Thank you - you are correct. We had a clone in there. I have updated the error log on Google Sheets.

I think there is a small problem with the "Completed time" column in GMAT Verbal link. When I enter time in minutes or seconds, it miscalculates the average time in the Analysis tab (turning out an average of 30 minutes for a question).

pyunika · Answer

HI,

Is there an update on error log for Verbal OG 2020th version?

Thanks in advance

LeoN88 · Answer

Hey, GOTO-> This page: GMAC © Official Guides - The Master Directory Click on any book that you want to practice using the error log. It'll redirect you to the specific forum. Cheers! Verbal '20 is not available as of now but you can use Verbal '19. For books (e.g. GMAT Advanced Questions Book Directory - 300 Questions) that don't have an error log, copy paste the question on Google, append it with ";Gmatclub.com" and

Sentence correction - 
OG 2020 Question- 786 has wrong answer choice in Error Log -

The question from GMAT is changed little bit and hence answer A doesn't make any sense :

786.   Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might,  but climatologists have indicated all along that precipitation, storminess, and temperature extremes are likely to have the greatest impact on people.

A.Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might,
B.Discussion of greenhouse effects has usually had as its focus whether Earth would get warmer and what the extent would be,
C.Discussion of greenhouse effects has usually focused on whether Earth would grow warmer and to what extent,
D.The discussion of greenhouse effects have usually focused on the possibility of Earth getting warmer and to what extent it might,
E.The discussion of greenhouse effects has usually focused on whether Earth would grow warmer and the extent that is,

Correct answer is  C

bb  do you agree ?
