Failed the theory? The plan to pass your retake 💪
Quick answer: First, context: failing the theory happens to more than half of candidates — it says nothing about your ability. Second, the good news: your €94.05 fee includes a free second attempt. The plan: identify which topics failed you (don't repeat random tests), review those topics with theory + targeted tests, and re-book only when official-mode mocks give you a stable 90% — especially if you failed «by one question»: that means you were cutting it fine, not unlucky.

What happens with your file now (table)
| Question | Answer |
|---|---|
| Do I pay again? | No — the fee includes 2 attempts; you only pay again (€94.05) after using both |
| When can I retake? | At the next available session; your school or the Jefatura assigns it |
| Is anything kept? | Yes, your file stays open; your medical certificate remains valid |
| What if I fail the second too? | A new €94.05 fee with two more attempts |
The 2-week retake plan
- Days 1–2: reconstruct the exam — which topics failed you? If you can't recall, take 2 mocks and let the statistics speak.
- Days 3–7: weak topics only: that topic's theory + its tests, reading every explanation.
- Days 8–12: 1–2 daily mocks in official mode (30/30, no aids). Target: stable 90%+.
- Days 13–14: light review and rest. At a stable 90%+, book it.
The classic post-fail mistake is «cramming» by repeating the same tests: you memorise answers, not concepts, and the DGT rephrases. On TraficoTest per-topic statistics tell you exactly what to review, and your pass probability confirms when you're truly ready.
«I failed by one question» — read this before retaking
It hurts, but the diagnosis matters: missing by one question means you arrived in the risk zone (80–85%), where luck decides. The fix isn't repeating the same way and crossing fingers — it's raising your base level to 90%+ so no trick question can sink you. The full rule is in how to pass first try — it applies equally to the retake.
Frequently asked questions
Do I pay again if I fail the theory?
Not the first time — the fee includes two attempts.
How long do I wait before retaking?
It depends on session availability at your Jefatura — your school manages it, or you do independently.
Is it normal to fail the DGT theory?
Yes — it happens to more than half; what matters is changing the method before the retake.
How do I know what I got wrong?
The official lookup only shows pass/fail — your school can give detail, and per-topic statistics from mocks reconstruct your weaknesses.
