Why does the test feel harder than my normal typing?

This is completely normal, and there's a straightforward reason for it.

Context and prediction

When you type an email, message, or document, your brain knows roughly what it's going to say. Context cues let you anticipate the next word before you've finished the current one. This predictive pre-loading speeds up your fingers — you're executing a plan, not reacting to each new word.

In a randomized word test, every word is unpredictable. Your brain must read the word, recognise it, retrieve the motor program, and execute it — all without any predictive shortcut. This extra cognitive step slows most typists down by 10–20%.

Unfamiliar words

Standard word banks contain common English words, but not words you necessarily type often. A marketing writer might type "strategy" many times a day and have a very fast motor program for it — but encounter "glib" or "wren" in a word test and slow right down. Your test score reflects general vocabulary coverage, not your specific professional vocabulary.

What this means for improvement

Improving your test score improves your real-world typing, because you're expanding and reinforcing the motor programs for a wider range of words. Your real-world typing speed is an easier ceiling to hit — improving your test score lifts both.

If you want to specifically improve speed for your actual work vocabulary, use custom text mode with your own documents.
