Microsoft Analyzing Big Data with Microsoft R (70-773) Practice Exam

Got me through on the first attempt. Four stars only because a handful of explanations felt thinner than the rest.

Realistic enough that exam day wasn’t a shock. Knocked one star off for a few outdated-feeling stems.

Not every question is perfect, but the set as a whole prepared me well. First-try pass.

If you’ve read the official guide once, jump straight into this bank. That’s the loop that worked for me.

Marked a bunch of questions, then filtered to those only. Fixed three weak areas in a weekend and sat the exam Monday.

I tracked domains in a spreadsheet while practicing. Once every column was green, I booked the test.

About 98% of what I saw on the real 70-773 lined up with topics I’d practiced. Felt fair, not spooky.

I compared a few providers; this one had fewer typos and better distractors. That decided it for me.

Scored in the mid-80s on my last practice run, booked the exam that week, and passed. Good calibration tool.

Passed after roughly 18 hours of practice here. I skipped a few easy domains and poured time into the hard ones.

Cleared 70-773 after bouncing off another site’s poorly written questions. Quality of stems matters.

Felt realistic without claiming to be a brain dump. That’s the balance I look for in prep tools.

Recommended it in our study Slack. Three of us sat 70-773 this quarter; all passed after using this set.

Useful main drill set. I’d add more timed full-length mocks, but the question quality is solid.

Not flashy, just solid practice. Instant feedback made it easy to fix weak domains before exam day.

The practice mode is what sold me — check the answer, read the explanation, move on. Cleared 70-773 without needing a second attempt.

I liked that difficulty varies. Easy ones build speed; the hard ones force you to think like the exam writers.

Passed with a comfortable margin. I wouldn’t skip the harder items — those taught the most.

The overlap people talk about felt real for me — roughly in the 98% ballpark on topics and framing.

Had about a month. Finished the set once, then a second pass on bookmarked misses. That was enough.

Used this during a busy on-call rotation — 20 questions when I could. Still cleared 70-773.

Clearer than the free PDFs floating around. Explanations actually cite the reasoning instead of just restating the answer.

Passed on attempt one. Biggest win was learning which options look right but fail a constraint in the stem.

I liked seeing both easy confidence-builders and nasty edge cases in the same bank.

I was weak on the longer case-style items. Drilling those here closed the gap; scored comfortably over the cut.

Did one domain at a time until accuracy stayed above ~80%, then mixed sets. Passed Analyzing Big Data with Microsoft R.

Good for last-mile prep if you already know the product. Don’t expect a full course; expect exam practice.

Short review: good questions, better explanations, passed 70-773. Moving on to the next cert next quarter.

Realistic stems, useful notes, no spammy upsells inside the practice UI. Appreciated the focus.

Took a week off between finishing the bank and the exam — reviewed notes only. Still felt prepared.

I work in a related role already, so I needed exam-style practice more than theory. This hit that need.

Practice questions alone won’t replace experience, but for Analyzing Big Data with Microsoft R they sharpened how I approach multiple-choice.
