As I am new to GMAT Club, I am not familiar with the
error log and how it works.
Can someone elaborate it
Thanks in advance

In brief, there are two dashboards related to your query:
1) In the dashboard of any question in GMATclub, there are two important keys:
a- the "
add question to pdf question list" (at the top right of every question)--> when used, it save the question into a list which are downloadable in pdf format later.
b- when you start the timer and answer the question, all details related to your performance in this question is saved under "
My error log", which in downloadable in excel format. Also an "add notes" button (
appears after answering) which allow you to add notes or hints about the question for yourself.
2) In your profile, you will find the "my
error log" tab, which access you to :
a- "
My error log" which is the list of questions answered and added notes to be downloaded in excel format
b- "My
error log stats" which show you your daily performance and estimated GMAT score from this performance.
c- "list of questions for pdf" which is the list of questions that you collected using the "
add question to pdf question list"
however, it is better to use the "my
error log" rather than the "add question to pdf question list" because of its flexibility and detailed data.
