Got my results today — passed! Wanted to write up what actually made the difference since most study advice I found online was either vague or trying to sell something.
What worked for me:
The most useful thing was drilling "DA" until I genuinely understood why each answer was right, not just which one was right. I stopped doing marathon study sessions and switched to 45-minute focused blocks.
The practice tests here matched the real exam difficulty closely. I found questions on "DA - Data Analyst" especially well-calibrated — the format and wording were similar to what I saw.
What didn't work: reading the official textbook straight through. Too dense. I'd read a chapter, take a practice test on just that chapter, review every wrong answer, then move on.
Final score: 73%. Time I had left over: about 26 minutes.
Happy to answer questions. You've got this.
If you're looking for a starting point, the free data analyst data mining is worth trying — the questions closely match what you'll see on test day.
The honest answer is: it depends a lot on your background.
If you're already working in this field, the DA exam is testing knowledge you probably use daily. The "DA" sections will feel familiar.
If you're coming in from outside, give yourself an extra 2 weeks and really focus on the practical application questions.
The practice tests here are worth doing repeatedly — I did the same test bank multiple times and found new questions I'd missed each time.
The advice about understanding why wrong answers are wrong — not just memorizing right ones — is genuinely the best DA advice in this thread. Rebuilt my prep around that and it made a real difference.
Failed first attempt, came back to this thread. The consensus on da practice test being the make-or-break area is right. Focusing almost exclusively on applied questions this time around.
Quick update: just cleared 79% on my most recent DA practice set using free data analyst data mining. Sitting for the real thing in 3 weeks. Feeling cautiously optimistic.
