Detailed Answer
Tests use three main text types: 1) Random common words (e.g., 'the cat ran' from a dictionary of 200–1000 words) – used by 10FastFingers. 2) Full sentences or paragraphs from literature/news – tests real typing with punctuation and capitals. 3) Pseudowords (Keybr.com) – random letter combinations to isolate finger movements. Professional exams (e.g., SSC) use actual paragraphs from official documents. For realistic practice, choose tests with punctuation, numbers, and varied vocabulary, not just simple word lists.
