About the assessment
About the Akuna Capital mental maths assessment
The Akuna Capital 80-in-8 practice format asks you to answer 80 mental-maths questions in 8 minutes, with a point added for a correct answer and a point removed for an incorrect answer on this tool. That scoring makes careless speed expensive: the objective is fast arithmetic that remains controlled enough to protect accuracy.
EverythingQuant also provides targeted addition/subtraction, division and multiplication modes. Use them to isolate the operation that is costing you the most time, then return to the full test once those calculations are more automatic. The score target shown in the tool is a practice benchmark, not a representation of an official hiring cutoff.

What you are training
Skills this practice is designed to build
Multiplication
Recall common products and decompose larger calculations without losing rhythm.
Division
Recognise factors and quotients quickly instead of relying on slow long-division style working.
Risk-adjusted pace
Because errors are penalised on this practice tool, speed should not come from indiscriminate guessing.
How to prepare
Use the tool deliberately
-
1
Find the slow operation
Use the targeted modes to identify whether addition/subtraction, multiplication or division is the main bottleneck.
-
2
Build automatic arithmetic
Repeat the weak operation until the common calculations require very little conscious effort.
-
3
Add short timed blocks
Practise retaining accuracy as the pace increases rather than jumping immediately to repeated full tests.
-
4
Validate on 80-in-8 runs
Track several full attempts and focus on stable improvement in both score and error rate.
