Counting wrong and empty number

We can get the total number of correct answers in the questions given by the system. but we can’t get the number of blank and wrong answers. Is there a solution you can suggest for this?

Hi Cemile,

To calculate the number of blank and wrong answers, you can add the following JavaScript code to the On Load event of the last slide as in the attached sample:

var total = prez.variable("apQuizTotalInteractions");
var correct = prez.variable("apQuizCorrectInteractions");
prez.variable("incorrectTotal", total - correct);
