Alternatively referred to as GWPM, which is short for Gross Words Per Minute, GWAM is short for gross words a minute and is similar to WPM except it does not account for any errors. GWAM is the overall typing speed regardless of how many errors you make. GWAM is often used as a measurement for users who are just learning to type and is later replaced by WPM.
GWAM can be calculated by typing text from an alternate source for 3-5 minutes and taking the amount of words divided by the minutes. For example, if you typed 400 words in five minutes, GWAM is calculated by dividing 400 by 5, resulting in 80GWAM.
