Education
Reading Speed Calculator (WPM)
Measures your reading speed in words per minute from how many words you read and how many seconds it took. Time yourself reading a passage with a known word count to get an instant WPM figure.
Education
Learning Retention Calculator
Compute learning retention rate as (retest score / initial test score) Γ 100, telling you what percentage of original mastery has survived the gap. The simplest forgetting-curve metric; useful for evaluating spaced-repetition schedules and study-method effectiveness.
