One purchase, this generation, yours to re-sit.
This OMPT-D paper follows the format below: 21 multi-step problems in 180 minutes, eleven chapters in syllabus order, the first four of which omptest.org marks as prerequisite. Official rows are from omptest.org; the last two describe this paper and its one big limitation.

| Questions | 21, all typed answers | omptest.org |
| Time | 180 minutes, timer starts only at Start | omptest.org |
| Pace | 8.6 minutes per question | omptest.org |
| Chapters | 11, asked in syllabus order | omptest.org |
| Answer field | Final answer plus your calculations in the note field; two graders score each step with a rubric. | omptest.org |
| Answer form | Exact: fractions, roots and powers unless a decimal is requested | omptest.org |
| Calculator | Only the extended on-screen calculator shared by OMPT-D and G; it does not apply order of operations | omptest.org |
| Formula sheet | None provided or allowed; special trigonometric values must be memorised | omptest.org |

Official rows are read from the OMPT-D syllabus, the pricing page and the OMPT knowledge base at omptest.org, checked 21 September 2026. The OMPT-D hub lists every chapter with its topic count.
Generation 4 is written at the difficulty of the OMPT-D sitting as omptest.org describes it: application and analysis items; omptest.org says the real test is harder than the practice material. The 21 questions keep the official chapter order and quota, and the hardest items sit late in each chapter, the way the real paper builds.
Keep it sealed until exam week and sit it once, on the clock, as the dress rehearsal, then spend the remaining days on the chapters it ranks lowest. Two graders will read your notes on the real paper; write this one as if they were reading.
The chapter quota is the same across the four OMPT-D generations. What changes is how many topics a single problem crosses: a generation-1 integration item is one definite integral, a generation-4 item is a volume of revolution that needs the intersection points first and a substitution in the middle. omptest.org describes the real OMPT-D that way, and Reddit candidates say the real paper is harder than even the official mock.

On the real OMPT-D your calculations in the note field earn partial credit, so the final answer is only part of the score. This paper cannot read notes. Write the method on paper as you sit it and compare it with the worked solution, which is laid out in the steps a rubric would pay for.
The OMPT-D uses the extended on-screen calculator shared by OMPT-D and G. What it can and cannot do is in our note on OMPT calculator rules.
None of these three is in the paper; they show the exact-form answer the OMPT-D field expects and the entry error each question invites. Three more, from other chapters, are on the free OMPT-D mock page, and a longer set is in our sample questions walkthrough.
OMPT-D example 1 · Integration
The region under y = √x from x = 0 to x = 4 is rotated about the x-axis. Find the volume of the solid.
Answer: 8π
Entry: Type 8pi. 25.13 is the rounded decimal and is marked down; forgetting to square √x before integrating gives (16/3)π, the most frequent slip on this topic.
OMPT-D example 2 · Geometry
Vectors a = (2, −1) and b = (3, 4). Find cos θ for the angle θ between them, in simplified exact form.
Answer: 2√5/25
Entry: Type 2sqrt(5)/25. The unrationalised 2/(5sqrt(5)) is equal but the official field expects the simplified form; 0.1789 is the decimal and is not exact.
OMPT-D example 3 · Trigonometry
A curve is given parametrically by x = 2cos t, y = sin 2t. Find dy/dx at t = π/6.
Answer: −1
Entry: Type -1. Dividing the other way round (dx/dt over dy/dt) also gives −1 here by coincidence, so the note must show the correct quotient to earn the method step.
Copied from the official OMPT-D: 21 problems, 180 minutes, chapter order, exact-form typed answers, no negative marking and no formula sheet. Not copied, and this matters more on OMPT-D than on any other variant: the note field that two omptest.org graders score step by step with a rubric. This paper grades the final answer only. Also not copied: the Sowiso engine, ProctorU and randomised values. Our generation-4 OMPT-D paper is written to the open-ended, multi-topic level omptest.org describes for the sitting.

Submit and the OMPT-D paper is graded instantly on the 21 final answers, each with a multi-step worked solution, and the eleven chapters ranked weakest first. Sit it in one 180-minute block; stamina is the OMPT-D problem the short drills cannot test. The paper stays in your account for re-sitting, with earlier scores kept. Prices include VAT. Refunds within 14 days of purchase, by email, to the original payment method.

The ladder
Generations climb toward the real sitting. Work them in order; each OMPT-D set uses entirely different questions.

The free OMPT-D mini-mock is a tenth of the paper at its real pace, scored in your browser. Sit that first; it tells you which generation to start on.
No. The OMPT-D generation 4 paper is original, written to the eleven-chapter OMPT-D syllabus at omptest.org, including Lissajous figures, vectors and volumes of revolution. Real OMPT-D problems are never released; omptest.org's paid practice material and mock are its only own-brand sources.
Yes. One purchase of €59.99 keeps the OMPT-D generation 4 paper in your account, re-sittable under the 180-minute clock. The 21 problems stay the same, so use a re-sit to time the problems you had to leave the first time.
The OMPT-D paper runs in a phone browser, but do not sit it there. OMPT-D problems need paper for working, and the real sitting requires a computer with a webcam and the Guardian browser plus up to three A4 scratch sheets. Rehearse it the way you will sit it.
The OMPT-D paper is graded instantly on the typed final answer, in exact form, with the normaliser used everywhere on this site. The real OMPT-D is different: two omptest.org graders score your note field against a step rubric, with results in eight business days. Our worked solutions show those steps so you can self-mark the method.
Use the report button under the OMPT-D problem. Every report is checked against the script that re-derives the generated answers, the paper is corrected, and you get a reply. The curated multi-step problems were re-derived by hand before release.
Generation 4 is our OMPT-D paper written to the open-ended, multi-topic level omptest.org describes for the sitting. Reddit candidates report the real OMPT-D is harder than even the official mock, so treat a generation-4 score as a floor and keep a margin above your cutoff.
No. A purchased OMPT-D paper stays in your account indefinitely. omptest.org's OMPT-D products (practice €95, mock €110, attempt €270) expire with the class year at the end of September.
Booking, proctoring and retake questions are answered on the help page; what the free sets cover for every variant is on the free OMPT practice test page.
