- 1 Read each passage once, at your natural pace.
- 2 The clock stops the moment you mark it read.
- 3 Answer a few questions — no peeking back.
- 4 Get your averaged velocity report & print it.

What this means
—
Benchmarks reflect widely-cited figures for adult silent reading of general prose (the average adult reads roughly 200–250 wpm with solid comprehension; ~300 wpm is typical of strong college-level readers). A result only counts as adequate when comprehension holds at 70% or above — the common floor used in reading-rate research, since speed without understanding isn’t reading.
