CompTIA Data+ Certification Exam

Best drill for the data visualization and reporting domain.

I had been doing ad hoc reporting and data work for years without a formal credential. The DA0-002 practice questions, especially around data concepts and mining techniques, matched the structure of my daily work closely. Passing it opened the door to a senior analyst role I had been eyeing for a while.

Coming from a non-technical background, the practice questions on data mining and analysis gave me the structure I needed to pass DA0-002 and land my first analytics role.

Data governance finally clicked. Cleared DA0-002 first try.

The data analysis and statistics sections were well-covered. The governance questions felt a bit lighter than what I saw on the actual exam, but solid prep overall.

Already working in business intelligence, I used this to fill real gaps in data governance and quality controls - areas the DA0-002 exam tests more heavily than I expected.
