just Passed with 866, for me was 1. Study all material in this community, @Will Needham has made a great job here, then I practiced with the trial, 2. Nikola Data Mozart blog and all his articles for DP600 are awesome, watched Priyanka's material, and I did all Practice Exams in Microsoft learn Platform... That worked for me...
