Measure your starting point
Choose a repeatable practice format—for example, one minute of ordinary sentences. Type naturally, finish the session, and take note of both WPM and accuracy. Use similar tests when comparing later results; a quick list of easy words and a full paragraph are not equivalent.
A single unusually fast result is less useful than a stable trend over several sessions. If the text is unfamiliar or includes more punctuation, your speed may change.
Make accuracy comfortable first
Speed comes from familiar movements, not frantic typing. When you rush and repeatedly backspace, you interrupt your rhythm. Try slowing down enough to type the next word correctly and consistently.
Type the sentence three times. Try to make the second and third attempts smoother, not necessarily faster.
Practise the parts that slow you down
Notice what breaks your rhythm: switching hands, capitals, punctuation, number keys, or unfamiliar combinations such as th, ing, and tion. Isolate one issue for a short practice block, then return to normal sentences.
Use a relaxed pace. If you miss the same combination repeatedly, practise it slowly before the next full test.
Use a short repeatable routine
Ten focused minutes are a useful starting point, not a required limit. If your hands feel tired, pause rather than forcing a longer session.
Compare progress fairly
When reviewing progress, compare the same duration and practice type, and pay attention to accuracy as well as WPM. A faster result with significantly more errors may not be an improvement for everyday work.
Do not expect improvement to be linear. Some sessions will be slower, particularly while learning better habits or unfamiliar keys. Look for consistency across multiple attempts.
Work towards a steady, comfortable rhythm. Once you can type accurately at that pace, allow speed to increase naturally. Avoid chasing a new personal best on every attempt.
Build the habit with real practice.
You don't need to remember everything today. A few careful minutes with the keyboard will help more than rushing through a long lesson.
