80 questions · 8 minutes · typed answers
+1 per correct answer, −1 per wrong answer, skips are free. Candidate-reported practice benchmark: ~60 net — not an official cutoff. Format and scoring may vary by region, role and recruiting cycle. Mix of 2-digit multiplication, decimals, large division, fractions, and multi-step arithmetic.
This is one fixed set — the same 80 questions in the same order for everyone, every time, so scores here are directly comparable.
Tip: answer with plain numbers (e.g. 4732, 0.75). Fractions like 2/3 are accepted too. Press Enter to submit.
What this test is
If you apply to trading firms, some version of this test is usually the first thing between you and an interview. Optiver's version — 80 arithmetic questions in 8 minutes — is the most famous, and firms like Akuna Capital and Flow Traders screen with close variants (Flow's is commonly reported as 75 questions in 8 minutes with multiple choice). The format sounds trivial until you do the division: you have six seconds per question, including reading it and typing the answer.

Same family of speed screens, different scoring. The Flow Traders math test is the closest MCQ cousin; CTC is a mixed-reasoning aptitude test, not a pure 80-in-8.
Why people fail it (and it's not arithmetic)
Nearly everyone who sits this test can do every individual question given 30 seconds. The three actual failure modes:
- Decision latency. The bottleneck isn't computing 47 × 62 — it's the half-second spent deciding how to compute it. Drilling makes the approach automatic, which is where the real speed comes from.
- Negative-marking discipline. Guessing is rational on tests without penalties — here it costs 2 net points per miss. Skipping feels like losing; on this format it's often the winning move.
- The last 90 seconds. Accuracy collapses at the end of the run as fatigue and panic set in. Short practice bursts never expose this — only full 8-minute simulations train it.
A 2-week training plan
- Days 1–3: untimed accuracy. Two-digit multiplication, fraction–decimal conversions, and long division with clean numbers. Zero errors before speed.
- Days 4–8: timed bursts. 20 questions in 2 minutes, repeatedly, tracking net score. Learn your personal skip threshold — the confidence level below which answering loses points on average.
- Days 9–14: full 80-in-8 runs, one or two per day, reviewing every miss afterward. Most people gain 10–15 net points in this phase from pacing alone.
Optiver 80 in 8 passing score
Search results often surface a single number (~60). That figure is a net score under negative marking, not raw correct counts. Net is almost always correct − wrong across the whole paper (skipped = 0). Example: 65 correct, 10 wrong, 5 skipped → net 55, not 65. When people ask for the Optiver 80 in 8 passing score, they almost always mean this net. Firms do not publish an official cutoff and it can move by role and region — treat ~60 as the number candidates cite most often, and aim comfortably above it. Use this free simulator to see what your net looks like under the real clock before you fixate on any candidate-reported benchmark.
The rest of the Optiver OA
80-in-8 is the famous first paper, not the whole assessment. Public prep sources (including detailed Zyvo-module write-ups) describe a multi-part online assessment that commonly runs around two and a half to three hours. Treat the list below as the publicly reported shape, not a guarantee — modules, timing, and whether you see every part can change by role and cycle.
| 80-in-8 | Mental arithmetic. This page. 80 questions · 8 minutes · commonly +1/−1. Some reports describe a 4-choice variant; this simulator is the typed form used for practice here. |
|---|---|
| NumberLogic | Number sequences. Widely cited as ~26 questions in 25 minutes, 5-choice, +1/−1, skips free, calculator allowed, with a commonly mentioned comfortable score around 15. Skill practice: daily sequences and the 60-question sequences & probability set. Those are independent drills, not a NumberLogic clone. |
| Beat the Odds | Probability. Commonly reported as 20 questions at 90 seconds each, 5-choice, +1/−1, no going back. Skill practice: daily probability & EV. |
| Zap-N | A set of short cognitive games (working memory, attention, planning, risk). Not a math paper. TradeMind does not clone Zap-N. The closest related drill here is Robot Games — Play/Pass expected-value decisions under a short clock. |
| Zap-Q | Untimed personality questionnaire (forced-choice statements). There is nothing useful to "practice" for it beyond answering honestly; we do not simulate it. |
If you only have time for one thing besides 80-in-8, do sequences and probability under a clock. Those two papers are where candidates who can already multiply two-digit numbers still fail the OA.

FAQ
What is the Optiver 80 in 8 test?
Optiver's famous first-round screen asks 80 mental arithmetic questions in 8 minutes — 6 seconds per question. Answers are typed (not multiple choice in the classic form), wrong answers cost a point, and candidates commonly cite a practice benchmark around 60 net. It is not an official cutoff. Several other trading firms use close variants of the same format.
What is the Optiver 80 in 8 passing score?
Firms do not publish an official cutoff, but candidates commonly report needing roughly 55–65+ net on an 80-question / 8-minute run (correct minus wrong under −1 negative marking) to feel competitive — with ~60 net the figure most often cited for Optiver-style screens. Treat any online number as anecdotal: aim comfortably above it, because nerves on test day routinely cost several points. Example: 68 correct and 7 wrong is 61 net (68 − 7), not 68.
What kind of math is on it?
Pure arithmetic: two-digit multiplication, decimals (0.25 × 4,000), large clean division (63,000 / 700), addition and subtraction of 3–4 digit numbers, and fraction operations that cancel neatly. There's no algebra and no word problems — it's raw speed and accuracy.
Is 60 out of 80 really the pass mark?
Around 60 net (correct minus wrong) is a candidate-reported practice benchmark for Optiver-style tests, not an official cutoff; formats and scoring can vary by role and region. Under negative marking, a 75-attempted / 68-correct run scores 61 — accuracy matters as much as speed.
Should I skip questions I'm not sure about?
Yes — this is the key strategic difference from tests without negative marking. A wrong answer costs you 2 points of net score (the +1 you didn't get, plus the −1 penalty). If you're not confident within a couple of seconds, skip and move on. Skips are free.
How does this page calculate my 80-in-8 result?
The web simulator records correct, wrong and skipped answers separately, then calculates net = correct − wrong; skips add zero. A run with 68 correct, 7 wrong and 5 skipped is therefore 61 net. The ~60 shown here is a candidate-reported practice benchmark, not an official Optiver cutoff, and formats can vary by region, role and cycle.
How do I get faster?
Three highest-ROI drills: (1) two-digit × two-digit multiplication until it's a single fluid motion, (2) instant fraction–decimal–percentage conversions (3/8 = 0.375 = 37.5%), (3) trailing-zero bookkeeping for big multiplications and divisions. Then run full 8-minute simulations to build pacing — most people's accuracy collapses in the final 90 seconds, and only full runs fix that.
Is the Optiver 80 in 8 multiple choice?
The classic Optiver-style 80 in 8 is typed answers, not multiple choice — you have about six seconds to type the number. Other firms and recruiting routes use multiple-choice variants of the same speed-arithmetic idea. TradeMind's Flow-style simulator uses a deliberately demanding 75 MCQ / 8-minute practice configuration; current formats can vary by region, role and cycle.
Is it 80 in 8 or 8 in 80?
Both phrases show up in search. The test is 80 questions in 8 minutes — 80 in 8. "8 in 80" is the same thing written backwards, not an 8-question test. This page is the 80-question / 8-minute typed format.
Is this the real Optiver test?
No. This is an independent practice reconstruction of the publicly described 80-in-8 style format (timing, typed input, negative marking). It is not Optiver's live assessment and does not reproduce real exam items. TradeMind is not affiliated with Optiver or any other firm.
What else is on the Optiver online assessment besides 80 in 8?
Public prep sources describe the Optiver OA as a multi-part Zyvo battery lasting around 2.5–3 hours: 80-in-8 mental math, NumberLogic sequences (~26 questions in 25 minutes), Zap-N (a set of short cognitive games), Beat the Odds (probability, commonly reported as 20 questions at 90 seconds each), and Zap-Q (an untimed personality questionnaire). Exact modules vary by role and year. This page keeps the 80-in-8 simulator and links free practice for sequences, probability, and EV-style games.
What is Optiver NumberLogic?
NumberLogic is the sequences module of the Optiver OA as publicly described: find the next number in a series. One widely cited shape is 26 questions in 25 minutes, multiple choice, +1/−1, skips free, calculator allowed. We do not clone that paper; the free sequences drill trains the same skill.
What is Zap-N?
Zap-N is a battery of short gamified cognitive tests (working memory, attention, risk-taking, planning) used in the Optiver OA. It is not a mental-math paper, and TradeMind does not ship a Zap-N clone. Robot Games on this site is a related Play/Pass expected-value drill — useful for the decision-under-uncertainty habit, not a recreation of any Zyvo mini-game.
