Nine years in data turned out to be worth more on SC-900 than I expected — but not everywhere. A domain-by-domain walkthrough of all four SC-900 skill areas, mapped honestly to a data-analyst background: what already transfers, what's brand-new, and where my real practice gap still sits.

The honest middle of cert prep. I scored 62% on a full-length SC-900 practice exam, lost momentum during a busy week, then got it back with targeted drilling. Here are my real numbers, where my misses still cluster (Compliance), the tools I'm using, and my final-week plan.

I added SC-900 to an already-full August — mid-CC-retake, deep in camp season. Here's the honest version: the free voucher I refused to waste, why I swapped down from SC-200, the 40% cold baseline that sealed it, and how two exams became one reinforcing study block.
