Subject: To build up speed and accuracy

                           There are a few games like Snow Typer, Type Fast, Fast Typer 2 and many more available in Rapid
                           Typing software that can help you build up speed and accuracy.




                    TYPING ACCURACY

            Typing accuracy is defined as the percentage of correct entries, out of the total entries typed. It can be:

                                                                                     Example
              In Terms of           Typing Accuracy
                                                                    Supposition                  Net Speed

                          Accuracy % = 100% - ((Words with   A person typed 50 words   Accuracy = 100 - ((6 * 100/50)
            Word          errors × 100%) / Total number of   per 2 mins. with errors in 6   => 88%
                          words)                             words.

                          Accuracy % = 100% - ((Characters   A person typed 250        Accuracy = 100 - ((30 * 100/250)
            Characters    with errors * 100%) / Total number of  characters per 2 mins. with   => 88%
                          characters)                        errors in 30 characters.

                          Accuracy %  = 100% - ((keystrokes   A person typed 200       Accuracy = 100 - ((40 * 100/200)
                          with errors * 100%) / Total number of  keystrokes per 2 mins. with
            Keystrokes                                                                 => 80%
                          keystrokes)                        errors in 40 keystrokes.




                    TYPING RHYTHM

            The Typing Rhythm means typing a character (keystroke) at equal intervals using the touch typing method. To control
            the constant typing speed, the Slowdown indicator, in terms of percentage is used as given below:

                                                                                     Example
              In Terms of          Slowdown Formula
                                                                      Supposition                 Slowdown

                           Slowdown % = (words with delay *   A person typed 60 words     Slowdown = (12 * 100) / 60
             Word          100%)/ Total number of words       per 2 mins. with delay in 12   => 20 %
                                                              words.

                           Slowdown % = (characters with delay  A person typed 250        Slowdown = (20 * 100) /

             Characters    * 100%) / Total number of characters   characters per 2 mins. with   250
                                                              delay in 20 characters.
                                                                                          => 8 %
                           Slowdown % = (keystroke delay *    A person typed 200          Slowdown = (40 * 100) /

             Keystrokes    100%) / Total number of keystrokes  keystrokes per 2 mins. with   200
                                                              delay in 16 keystrokes.     => 8 %
