Scoring Logic for Mark the Word

Hi!  I wonder if you could add a scoring logic that only calculate the # of correct answers, in addition to the current logic (i.e. # of correct minus # of wrong, AND minus # of missing).  E.g. with the current logic, if users miss a correct answer, they get 1 pt deduction, but if they mark a wrong word, they'll get 2 pts deduction, because not only the missing word get deducted, but also the wrong marking get deducted as well.  The current logic might be a little tricky for teachers to figure out.
