Detailed Answer
To boost speed in 2–4 weeks: 1) Fix bad habits – ensure proper home row posture. 2) Practice 20 minutes daily, never skipping. 3) Use Keybr.com – it identifies your weakest letters and drills them. 4) Take 1-minute sprint tests, but don't neglect accuracy (target 95%+). 5) Learn common English n-grams ('tion', 'ing', 'the') to type them as chunks. 6) Use all fingers – stop overloading index fingers. 7) Listen to metronome at 10% above your current WPM (e.g., if 40 WPM, set 44 beats/min; each beat = one keystroke). 8) Practice with punctuation and capitals. Quick gains come from eliminating pauses, not moving faster. Avoid looking at keyboard – tape over keys if needed.
