OMPT-G full mock exam, generation 3: 26 questions in 180 minutes
One rung below the summit. The questions chain more steps together and the coverage tightens toward the material that decides scores — close enough to the real thing to expose a shaky technique while you still have time to fix it.
Original questions, written by OMPT Practice. Official figures last verified 21 September 2026.
You type every answer and the grader checks it the way the real sitting does. There is no multiple choice to lean on.

What an OMPT-G generation 3 sitting is like
Generation 3 is one rung below the sitting. The chapter quota is the same, but the questions chain three or four steps and the coverage tightens toward the material that decides OMPT-G scores. Expect fewer single-operation items and more that start in one chapter and finish in another.
Sit it two to three weeks before your booked test, with the full 180 minutes and no pauses. If a chapter still leaks here, there is time for a drill cycle before generation 4. The chapter ranking after this paper is the most reliable prediction of where the real paper will cost you.
Chapter mix of OMPT-G generation 3
All four OMPT-G generations share the same chapter quota, including the two science chapters. The generations differ in how many steps a question needs: a generation-1 chemistry item balances one equation, a generation-4 item balances a redox half-reaction and asks for the pH that follows.
Official weights are from the OMPT-G learning-assessment page at omptest.org. Each drill link opens a free topic page with its own ten-problem set; the full list is on the topics page.
How to enter answers on the OMPT-G paper
OMPT-G grades the answer field first and reads the optional note only for partial credit. Physics and chemistry answers use the same exact-form rules as the maths, with the unit implied by the question.
Fractions and decimals
A fraction question wants a reduced fraction (7/16), a decimal question wants a decimal point, and swapping them costs the mark. The real calculator shows decimals only, so keep the fraction arithmetic on paper.
Roots and constants
Reduce the root and clear the denominator: 3+sqrt(5), 8pi, 2sqrt(5)/25. Numeric approximations of π, e and roots are wrong where exact form is asked.
Powers
x^2 and x² are read the same; so are cm^2 and cm². A negative exponent stays a power or becomes a fraction, never a decimal.
Multiple answers
List all solutions, comma-separated, in the order the question asks. A missing second root or angle is an incomplete answer, not a half-right one.
Intervals
Give inequalities as -5<=x<-2 or as [-5,-2). The bracket type carries meaning: round excludes the endpoint, square includes it.
Units and prefixes
Type the bare number; a unit the question named is stripped on grading. Do not add words such as metres or joules.
Working
On OMPT-D and OMPT-F the real paper scores your note field step by step; on B and G a note is optional; on A, C and E there is none. This paper grades the answer field only on every variant.
Invalid input
A half-filled template or an unclosed bracket on the real paper is flagged orange, stored and graded by hand. Here it is simply marked wrong, so check the syntax before you move on.
The OMPT-G 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.
Three worked OMPT-G examples in the answer form this paper grades
None of these three is in the paper; they show the exact-form answer the OMPT-G field expects and the entry error each question invites. Three more, from other chapters, are on the free OMPT-G mock page, and a longer set is in our sample questions walkthrough.
OMPT-G example 1 · Chemistry
Balance the equation Al + O₂ → Al₂O₃. Give the three coefficients in order.
Oxygen: the right side has 3 O per formula unit and the left has 2 per molecule. The lowest common multiple is 6: 3 O₂ and 2 Al₂O₃.
Aluminium: 2 Al₂O₃ contain 4 Al, so 4 Al on the left.
4Al + 3O₂ → 2Al₂O₃. Check: 4 Al and 6 O on each side.
Answer: 4, 3, 2
Entry: Enter 4,3,2. Changing a subscript (writing AlO₃) to make the count work is the classic error; only coefficients may change when balancing.
OMPT-G example 2 · Geometric calculations
A circle has equation x² + y² − 6x + 4y − 3 = 0. Find its centre and radius.
Complete the square in x: x² − 6x = (x − 3)² − 9.
Complete the square in y: y² + 4y = (y + 2)² − 4.
So (x − 3)² + (y + 2)² = 3 + 9 + 4 = 16, giving centre (3, −2) and radius 4.
Answer: centre (3, −2), radius 4
Entry: Type (3,-2) and 4. Reading the centre as (−3, 2) from the signs in the equation is the usual slip; the centre has the opposite signs to the linear terms.
OMPT-G example 3 · Physics: mechanics
A 2 kg object speeds up from 3 m/s to 7 m/s. How much work was done on it?
Work-energy theorem: W = ΔKE = ½m(v² − u²).
½ × 2 × (49 − 9) = 1 × 40.
W = 40 J.
Answer: 40 J
Entry: Type 40. Squaring the difference of the speeds, ½ × 2 × 4² = 16, is the error to watch for; the theorem uses the difference of the squares.
How OMPT-G generation 3 compares with the official OMPT-G
Copied from the official OMPT-G: 26 questions, 180 minutes, chapter order, exact-form typed answers, no negative marking and no formula sheet. Not copied: the extended calculator shared with OMPT-D, the optional note field that omptest.org's graders read for partial credit, the Sowiso engine, ProctorU and randomised values. omptest.org publishes no separate difficulty note for OMPT-G; its practice material is the reference, and our generation-4 OMPT-G paper is written to that level.

What the OMPT-G score report shows after you submit
Submit and the OMPT-G paper is graded instantly, 26 answers with worked solutions, and the eleven chapters ranked weakest first, so a mechanics or chemistry gap shows up separately from a maths one. 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 refund and access wording in full is on the terms page. Bundles that pair this paper with another generation are on the plans page.
The ladder
Other OMPT-G generations
Generations climb toward the real sitting. Work them in order; each OMPT-G set uses entirely different questions.
No. The OMPT-G generation 3 paper is original, written to the eleven-chapter OMPT-G syllabus at omptest.org, from linear formulas through mechanics and chemistry. Real OMPT-G questions are not published.
›Can I retake OMPT-G generation 3?
Yes. After one purchase of €39.99 the OMPT-G generation 3 paper stays in your account and can be re-sat under the 180-minute clock. The 26 questions are fixed, so a retake confirms fixes; the next generation gives new questions.
›Does the OMPT-G paper work on a phone?
The OMPT-G paper runs on a phone, but chemical equations and radian answers are awkward on a phone keyboard, and the real OMPT-G is sat on a computer with a webcam under the Guardian browser. Use a laptop for at least one full sitting.
›How is the OMPT-G paper graded?
The OMPT-G paper is graded instantly on the typed answer in exact form, with units the question asked for stripped by the normaliser (20 and 20m both pass). The real OMPT-G is checked by software and then by omptest.org's graders within eight business days, with partial credit possible from a note.
›What if an OMPT-G question is wrong?
Use the report button under the OMPT-G question. Reports are checked against the script that re-derives each generated answer, the paper is corrected, and you get a reply. The curated mechanics and chemistry items were re-derived by hand before release.
›Is OMPT-G generation 3 at real-test difficulty?
No. OMPT-G generation 3 is the near-exam tier, 1 rung below generation 4, which is written at the level omptest.org describes for the real OMPT-G. This paper shows whether the gap is in the maths or the science chapters.
›How long is the OMPT-G paper available?
A purchased OMPT-G paper does not expire. omptest.org's OMPT-G products expire with the class year at the end of September, so a paper bought here in one admission round still works in the next.
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.
