hi bb! this is VERY helpful I must say. I'm currently using this template for my prep and it helps me to track my error log so I don't have to revisit every questions every single time

but I just wondering, will the Verbal and Data Insight review error log will be available as well? cz I've been running out of OG questions and wondering whether I should buy them or not (one of the consideration is GMATClub error log)

Thanks so much!

thank you soo much for putting this together

There is a formula error in the error log where its checking the next question rather than the current question - i suggest trying to input your answer for 15 and it will outline the answer for 16 and fill the details for 16 in the error log.

Thank you! We used to have a header row in there and I deleted it without realizing it would mess up the formulas.
Fixed! Should be accurate now.

Hi. Yes, we are working on them but it is taking time to go through every question (manual process unfortunately).
Welcome any help as kingbucky is mostly single-handedly going through 2K questions at this point :shock:
