Quick answer: OET Reading and Listening each have 42 questions, and your raw marks convert to a scale from 0 to 500. Grade B, the score most regulators demand, starts at 350, which is roughly 30 correct answers out of 42. Near the Grade B border, one raw mark moves your score by about 10 to 12 points.

How this calculator works
You finish a practice test and get a number like 28 out of 42. But the exam does not speak in raw marks. It speaks in the 0 to 500 scale, and your visa, your registration and your future speak in grades. This calculator translates. Enter your Reading or Listening raw score and it returns your estimated scaled score, your grade, and your exact distance from 350.
One honest note, and it applies to every calculator on the internet including this one: OET does not publish the official conversion table. Anyone showing you an exact figure is showing you an estimate. Mine is built from tracked student results and it uses the same conversion as the mock test platform, so your numbers here and your numbers there always agree.
The grade bands
| Grade | Score | Raw marks, roughly |
|---|---|---|
| A | 450 to 500 | 36 or more out of 42 |
| B | 350 to 440 | around 30 out of 42 |
| C+ | 300 to 340 | around 27 out of 42 |
| C | 200 to 290 | below that |
Most regulators ask for Grade B at 350. Some accept C+ in one skill, as the NMC does for Writing, and Australia now asks for 360 in Reading and Speaking, which is above Grade B. Check your own regulator with the eligibility checker rather than assuming 350 is enough everywhere.
What your number means, and what to do with it
A score without a plan is just a feeling. Here is the honest map. At 25 or below, the foundations need rebuilding, months of system work, not weeks of tips. At 26 to 29, you are close, and precision closes the gap: targeted training on your exact leak. At 30 or above, you are in Grade B territory and a short sharp sprint finishes the job, because near the border every single mark is about ten points, and careless marks are the only thing standing between you and the grade.
And know exactly where the marks come from. The Reading system runs on the Grade B Equation: 18 in Part A, 4 in Part B, 8 in Part C is 30 out of 42. The Listening system runs on its own: 22 or more in Part A and 4 or more in Part B clears the exam before Part C begins.
Failed one sub-test? Check the clubbing rules before you rebook.
Many regulators let you combine two sittings, the UK NMC, Australia and New Zealand. Some never do: Ireland, and every doctor route. The rules, the floors and the windows, verified against the official pages, are here. → OET clubbing rules 2026
One number is a guess. Two numbers are a diagnosis.
The score from someone else’s practice test tells you where you were. The free mock tests tell you where you are, on current exam difficulty, marked instantly, with your grade estimate and your per part breakdown, so you see exactly which part is leaking. That breakdown is what turns a number into a plan.
How these tools stay accurate
Every number here was read from the regulator’s own page on 2 September 2026, not from a forum, an agent or a WhatsApp group. The three tools share one rules file, so when a regulator moves, all three move together on the same day. Australia moved in April 2026 and this is what that looks like when it is handled properly. And one line that never leaves these pages: the checker predicts, the regulator decides. Confirm with your regulator before you apply.
