About this test
A 10-item screener blending three classic formats: number series, word problems with percentages and ratios, and basic arithmetic / logic. Designed for five minutes of self-reflection, scored simply as a percentage.
Methodology
A brief numerical-reasoning screener inspired by the sequence / word-problem format common to aptitude assessments. Items authored by TEST-YO!, not drawn from SHL, Kenexa, or any proprietary test battery.

- Quant · Spreadsheet brain
- Numbers fall into place before you've finished reading. Annoying.
- Whiz · Numbers-fluent freak
