A mock exam score answers one question: how many you got right today. Passing the DEA-C01 depends on more than that. Candidates who score well on mocks and still fail usually ran into one of four problems that a single number hides.
Four ways a mock score gives a false signal
- An average hides a weak domain. 75% overall can include one domain at 40%. Data Ingestion and Transformation alone is 34% of the DEA-C01 exam, so a gap there costs far more than a good overall score suggests.
- Repeated mocks reward memory. Retake the same question pool and the score climbs because you recognise the questions, not because you know the material.
- One sitting is noisy. A short mock samples only a few questions per domain. Two lucky guesses can move the score by several points.
- Difficulty varies. A mock that is easier than the real exam inflates your confidence right before you book.
What the Edureify readiness score adds
Your readiness score weights every domain the way the DEA-C01 exam does, and flags any domain below the 60% minimum even when your overall score looks safe. Each retake uses fresh questions, so a rising score means you learned something rather than remembered it. And it turns your gap into time: how many focused hours stand between you and the 90% ready line, and the date you get there at your pace.
| Mock score only | Edureify readiness score | |
|---|---|---|
| What it measures | Questions right in one sitting | Weighted performance in every domain |
| A weak domain | Hidden inside the average | Flagged below the 60% minimum |
| Retakes | Often the same questions | Fresh questions, trend tracked |
| "When will I be ready?" | No answer | Hours to go and a ready-by date |
When to book the DEA-C01 exam
Book when every domain is above the minimum and your readiness has held at 90% or more across at least two attempts with different questions. One high score can be a good day. Two in a row is a pattern you can rely on. With the exam fee listed at $150, that second check is cheap insurance.
