GMATCLUB Members, I have put together a new Error for preparing for the GMAT. It is a simple excel based error log. The main difference from other error logs is that you can calculate your ability for each topic. Error_Log_Ability_Accuracy.xlsx How to calculate weights/Difficulty level : To find the accurate ability for each section, it is really necessary to put correct weights for each questions. Sample way to enter the weights for the questions. I have segregated the questions based on the following, Easy(500 Level)- 2 Medium(600 level)-4 Hard(700+Level)- 6. In many test prep companies online question banks- the questions are segregated with the difficulty level. So you can use that measure to enter the weight in the Log. If you are using GMATclub forum to answer the questions- You can find out the difficulty level of the questions using "tags" or more appropriately use the GMATclub timer feature. Since it gives the difficulty level questions based on the attempts. If you are using OG Online tool to practice- The questions are segregated using the difficulty level as well. So use that feature to enter the weight. Now about the log. Ability to answer 700+ level questions gets your high score on the GMAT. The ability is also mentioned in the ESR. So, I felt it is good to have an error log to calculate our ability as a main measure instead of accuracy. This error log focuses on that aspect. In egmat workshop, I got the formula sheet which was used to calculate the ability on that workshop questions. So I used that logic to make this error log. Thanks, Egmat!! :-D Also, the scholaranium of egmat uses this ability for the questions. Give it a try. Below are the screenshots from this error log.

Can you please guide me to use the error log?
What all information do I need to enter in the log manually?

Great error log Gnpth and thanks for all the hard efforts for creating this.
One silly question regarding timer as I'm not seeing this being mentioned in instruction.
How do you start a timer as I'm not seeing anything start or stop or reset by clicking on the buttons after inputting some values in the red button "timer"? Appreciate for your time and reply. Thanks
