Logistics, scoring, and pacing

Lesson 3 of 3 in The DEA-C01 Exam: Blueprint, Logistics, Strategy.

The arithmetic on this exam is unusually clean: 65 questions in 130 minutes is exactly two minutes each. That makes the checkpoints trivial to hold in your head while you work — question 20 by minute 40, question 40 by minute 80, all 65 touched by minute 110 — which leaves twenty minutes for flagged items.

Spend those two minutes unevenly on purpose. A recognition item ("which service catalogs schemas?") should cost thirty seconds. A five-option multiple-response item with a three-sentence setting will cost three or four minutes and is still worth one mark. The first pass therefore runs faster than the average, banking time rather than consuming it — and every item gets a committed answer before you leave it, because an unanswered question scores exactly as a wrong one.

A line chart of minutes elapsed against question number for three pacing strategies on a 130-minute, 65-question exam. The flat two-minutes-per-question line rises steadily and reaches 130 minutes exactly at question 65, leaving no review time. The two-and-a-half-minutes-per-question line rises more steeply and crosses the 130-minute limit at about question 52, meaning 13 questions are never reached. The two-pass line rises at one minute forty seconds per question, reaching question 65 at about 108 minutes, and then flattens as the remaining 22 minutes are spent on flagged questions rather than new ones.

The clock, drawn three ways. At a flat 2:00 you finish on the final second with nothing left for review; at 2:30 you run out around question 52; a first pass at 1:40 reaches the end by minute 108 and leaves 22 minutes for flags.

The two-pass run is the strategy the arithmetic recommends, and it has three rules. On the first pass, answer what you know and flag anything you are not confident in — but answer it anyway. On the second pass, visit only flags, in the order you flagged them. And with five minutes left, stop re-reasoning and start sweeping for anything still blank.

The reason flagging works here is that the exam interface lets you revisit, and the reason answering before flagging works is the scoring rule: a blank and a wrong answer cost the same, so a provisional guess is free insurance against never getting back. Candidates who flag without answering are the ones who lose four marks to a clock they thought they were managing.

Format and timing

  • 65 questions, 130 minutes — exactly 2:00 per item, including every re-read.
  • 50 scored, 15 unscored. The unscored items are not identified. Treat all 65 as live.
  • Two response types only: multiple choice and multiple response. No sequencing, no matching.
  • Items can be flagged and revisited, so plan a two-pass run rather than one perfect pass.
  • Unanswered is scored as incorrect; there is no penalty for guessing. Never hand back a blank.

Scoring

  • Scaled 100–1,000, pass at 720. That is the associate line — do not carry a 750 target over from a specialty exam.
  • Compensatory: you do not need a passing score in each section, only on the exam as a whole.
  • The score report may contain a table classifying performance per section. With roughly nine to seventeen scored items per domain, read it as a hint about study priorities, not as a measurement.
  • A scaled score is not a percentage of questions answered correctly, so there is no fixed "how many can I get wrong" — the mapping is set by the standard, not by arithmetic you can do in the room.

Before the day

  • Delivered at a test centre or by online proctoring; the fee and the current duration are on the certification page, and logistics change independently of the content outline.
  • Book a time of day when you read carefully. This exam is 130 minutes of close reading, and the failure mode is skimming a constraint, not forgetting a service.
  • Check identification, retake and recertification rules on AWS's own certification policy pages rather than a forum post.
  • The exam guide is short and free. Read it end to end twice — once now, once in your final week.
