Hi,
Before my recent GMAT Focus attempt, I took the GMAT in January 2017. I scored 780.
I took GMAT Focus on the 29th of November, 2023. I scored 735, which corresponds to 770 on the classic edition of the GMAT (per mba.com).
I conducted a webinar recently in which I shared my preparation (which was minimal and hardly useful for others to know), analytics for my mocks and my actual GMAT attempt (a little useful), and a few tips on how you too can score 100 percentile on the GMAT (much more useful).
Here's the recording of the webinar: (In the description of the video on youtube, you can find the links to the google sheet containing analytics and to the pdf of the ppt I used in the session.)
Regards,
Chiranjeev
