80 in 8 practice test

Eighty arithmetic questions, eight minutes: six seconds a question. This is the shape of the timed numerical tests many trading firms use in early rounds. Take it below — no account, nothing to install.

What's in it

• Addition of two two-digit numbers: 47 + 86.
• Subtraction with answers that never go negative: 112 − 58.
• Multiplication up to 19 × 12: 17 × 8.
• Division that always comes out whole: 132 ÷ 11.

The mix is random and changes every attempt, so you can retake it as often as you like. Real tests vary: some add decimals, fractions or negative numbers, and some take marks off for wrong answers. Treat a mistake here as costing you a question.

How to get faster

• Make the facts automatic. Every second spent on 7 × 8 is a second gone. If any table is slow, fix it first: the 7s, the 8s, all tables to 20.
• Add left to right. 47 + 86: 40 + 80 = 120, 7 + 6 = 13, so 133. See addition speed.
• Subtract by counting up. 112 − 58: 58 to 60 is 2, 60 to 112 is 52, so 54.
• Split awkward products. 17 × 8 = 10 × 8 + 7 × 8 = 136. More in multiplying in your head.
• Read division as multiplication. 132 ÷ 11 is “11 times what is 132?”
• Don't stall. If a question isn't coming, a guess and move on usually beats ten seconds of staring — unless the test penalises wrong answers.

A practice plan

Take the test once to get a baseline. Then spend most of your time on the specific operation that's slowest, in short daily sessions, and retake the full 80 in 8 every few days to see the score move. R3CK0N's Math mode times each operation separately and charts your pace over weeks; Quant Prep has a dedicated trading-test sprint.

Frequently asked questions

What is an 80 in 8 test?

A timed arithmetic test of 80 questions in 8 minutes — six seconds a question. Candidates for trading and market-making roles commonly report this format in early-round numerical tests.

What is a good score?

Firms do not publish cut-offs. Candidate reports usually put a competitive score in the 60s or higher, with few mistakes, so aim to finish with time to spare rather than just to pass.

Is this the official test?

No. It's an independent practice test in the same shape. R3CK0N is not affiliated with any firm.
