    Hello or good evening everyone,

    This is indeed a simple rule of three.

    The method:

    - take the score out of 13 and divide it by 13

    - you get a number less than 1 (like 0,something)

    - take this number and multiply it by 20

    - the result is the score out of 20.

    And there you go!
