Original number-entry practice · Timed results and full revision free
Choose whole numbers, decimals or leading-zero codes for a real 60-second number-entry round. See confirmed-equivalent KPH, exact-entry KPH, entry errors, character accuracy and every copied row. All three complete practice guides are free.
3 modes · Real 60-second rounds · No signup
Choose one of three original synthetic lists. After Start, copy one displayed value at a time and confirm with Enter or the button. Keep decimal points and leading zeros exactly as shown. Edit before confirming; a blank confirmation is a wrong entry. Pasting and dropping text are blocked. Finish input-method composition before confirming. Only confirmed text before the 60-second deadline is scored; an unfinished tail is excluded. Hiding the page or a detected clock discrepancy cancels and clears the round. Reload does not resume a timed attempt.
Entries stay in this page’s memory. Timed drafts do not resume: changing tabs, reloading or changing language requires a fresh round. Number-row and touch input are welcome for practice; browser codes cannot certify a physical keypad.
Practise copying numbers with real input rather than multiple-choice preferences. Pick a whole-number, decimal or leading-zero reference list; each offers 240 fixed, independently constructed synthetic values. One attempt is one uninterrupted 60-second round in your chosen mode. All three full guides are available before and after practising, with worked examples and explicit units. The exercise does not assign a personality, a hiring grade or a certified keypad speed.
Every complete round lasts 60 seconds. Confirmed-equivalent KPH = (characters in confirmed entries + one separator per entry) ÷ 60 × 3,600. Exact-entry KPH uses only entirely correct entries, including their separator. Backspace and discarded characters are not throughput; a confirmation button represents the same one separator as Enter, not a measured physical keypress. Entry error rate = wrong confirmed entries ÷ all confirmed entries. Positional character accuracy = matching character positions ÷ the sum of the larger source/entered length for each confirmed entry. With no confirmed entries, accuracy and error rate are unavailable.
These fixed synthetic numbers, task rules and worked guides are independently authored by FermatMind for local practice. Scores describe this edition, device, mode and uninterrupted minute, with prior exposure and any assistance affecting comparability. They are not employer norms, hiring certification, an IQ measure or a prediction of job performance. Browser key codes describe reported events rather than proving a physical keypad. Inputs stay in this page’s memory, with no answer upload, saved draft, answer URL or answer analytics. Hiding the page or a detected clock discrepancy cancels and clears the round; reload starts again.
Each mode has worked examples, units, editing rules and device limits. Read them before starting. They are not score bands or private attempts, and no speed is required to unlock them.
Whole-number entry: full practice guide with an original worked minute, exact-entry and character denominators, editing rules, device limits and a small optional review routine.
Decimal entry: full practice guide with an original worked minute, exact-entry and character denominators, editing rules, device limits and a small optional review routine.
Leading-zero reference codes: full practice guide with an original worked minute, exact-entry and character denominators, editing rules, device limits and a small optional review routine.

A physical keypad is suitable for keypad practice, but a number row or touch keyboard can also enter the source. The result reports only browser-observed digit events as Numpad, number row or other/unknown. Virtual and accessibility devices may imitate codes, so this is not hardware verification. Input method, prior exposure and device affect comparisons.
Edit before confirming. Pasting and dropping text are blocked. There is no pause or saved timed draft: hiding the page cancels and clears the round, and reload starts again. Unconfirmed text at the deadline is shown separately and not scored. All completed-round rows remain available in the current page until you clear or restart.
No. This edition reports what happened in one local 60-second practice with fixed synthetic material. It has no population norms, pass mark, hiring certification or conversion to another provider’s KPH. It cannot establish IQ, general attention or job suitability.
All calculations, copied-row reviews and three complete bilingual guides are free without signup, email or an earlier assessment. Entries remain in this page’s memory and are not sent to analytics or encoded in URLs. Optional further practice or a separate RIASEC interest assessment requires its own task; this speed is never converted into an interest or personality result.
These documents describe browser API behaviour and limits. They do not validate this number bank, training outcomes or hiring use. The numbers, rules and full guides are original to this edition.
