How WPM (Words Per Minute) and Accuracy are Calculated (Teacher & Student)

WPM (Words Per Minute) is a calculation of exactly how fast someone types with no error penalties. The gross typing speed is calculated by taking all words typed and dividing by the time it took to type the words in minutes. A "word" is equivalent to five keystrokes (including spaces, numbers, letters, and punctuation marks). 

To give an example: if you typed 300 characters in 2 minutes, your Gross WPM  typing speed would be (300 characters / 5) / 2 min = 30  WPM. 

Accuracy\Typing accuracy is defined as the percentage of correct entries out of the total entries typed. If you typed 300 characters with 16 errors, you typed 284 correct entries, and your accuracy percentage would be  284 / 300 = 95%.
