Free Optiver 80 in 8 practice test

80 typed mental-math questions in 8 minutes. A correct answer scores +1, a wrong answer −1, and a skip 0. Free in the browser, with no signup and an instant net score. Candidate-reported practice benchmark: ~60 net (not an official cutoff). Format and scoring may vary by role, region and recruiting cycle. Independent practice based on publicly described assessment formats. Not affiliated with or endorsed by Optiver.

What this test is

Many trading firms put a timed arithmetic test before the first interview. Optiver's version is 80 questions in 8 minutes. Akuna Capital and Flow Traders use close variants (Flow's is commonly reported as 75 multiple-choice questions in 8 minutes). That leaves six seconds per question, including reading it and typing the answer.

Optiver 80 in 8 compared with Flow Traders and CTC

All three are timed screens with different scoring. The Flow Traders math test is the closest multiple-choice equivalent. CTC's test mixes numerical, spatial, verbal and logic questions.

Where candidates lose points

Most candidates could answer any single question given 30 seconds. They lose points in three ways:

• Decision latency. Computing 47 × 62 is quick once you know the method. The half-second spent choosing how to compute it adds up. Drilling makes that choice automatic.
• Negative-marking discipline. Guessing makes sense on tests without a penalty. Here a wrong answer costs a point, as much as a right one earns, so an answer only helps on average when you are more likely right than wrong. Skip the rest.
• The last 90 seconds. Accuracy falls near the end of the run as fatigue and panic set in. Short practice bursts do not show this; full 8-minute simulations do.

A 2-week training plan

1. Days 1 to 3: untimed accuracy. Two-digit multiplication, fraction-to-decimal conversions, and long division with clean numbers. Get to zero errors before adding speed.
2. Days 4 to 8: timed bursts. 20 questions in 2 minutes, repeatedly, tracking net score. Learn your skip threshold: the confidence level below which answering loses points on average.
3. Days 9 to 14: full 80-in-8 runs, one or two per day, reviewing every miss afterward. Most people gain 10 to 15 net points in this phase from pacing alone.

Optiver 80 in 8 passing score

The number most often quoted is ~60. It is a net score under negative marking, almost always correct − wrong across the whole paper, with skips counted as 0. For example, 65 correct, 10 wrong and 5 skipped is a net of 55. Firms do not publish an official cutoff, and the bar can differ by role and region. Treat ~60 as the figure candidates cite most often and aim above it. Run the simulator above to see your net under the same 8-minute clock.

The rest of the Optiver OA

80-in-8 is the first of several papers. Public prep sources, including detailed write-ups of the Zyvo modules, describe a multi-part online assessment that commonly runs two and a half to three hours. The list below is that reported shape. Modules, timing, and whether you see every part can change by role and cycle.

If you only have time for one thing besides 80-in-8, do sequences and probability under a clock. Candidates who are already fast at arithmetic often fail the OA on those two papers.
