Focus Score Test — Real Timed Attention Test
A real in-browser go/no-go attention test with a measured, timed score · free, no signup
Letters will flash one at a time. Tap/click the stage for every letter EXCEPT the letter X. Don't tap when you see X. 24 rounds, about 20 seconds.
Focus Score Test
This is a real, timed sustained-attention test, not a self-report quiz: letters flash one at a time and you tap for every letter except X, across 24 rounds. It measures your actual reaction speed on go-trials and your accuracy at withholding taps on no-go (X) trials — a classic go/no-go paradigm used in real attention research, simplified for the browser.
Your measured average reaction time is converted to a percentile using a stated normal-distribution model anchored to an assumed ~400ms average go/no-go reaction time, blended with your raw accuracy into a single Focus Score out of 100.

Tips for the best results
- Sit somewhere without distractions for an accurate reading.
- Use a mouse or touchscreen tap rather than a trackpad drag for cleaner timing.
- Retake it a few times — attention naturally varies by time of day.
Common mistakes to avoid
- Tapping impulsively on every letter including X, which tanks accuracy.
- Testing while multitasking, which skews the measurement.
- Treating a single run as a permanent label rather than a snapshot.

Frequently asked questions
Is this a self-report quiz?
No, it's a real timed test — your actual clicks and reaction times during the test are measured, nothing is self-reported.
What's a go/no-go test?
A classic attention-research design where you respond to most stimuli (go trials) but withhold responding to a specific one (no-go trials, here the letter X).
How is the percentile calculated?
Your measured average reaction time is compared against a stated, assumed ~400ms average go/no-go reaction time using a normal-distribution model.
Is this a clinical ADHD or attention diagnosis?
No, it's a fun, simplified attention test for self-reflection, not a medical or clinical assessment.
Is my timing data stored?
No, all timing and scoring happens locally in your browser and is never uploaded.
