I would some help understanding how a quiz with grated questions gets calculated by articulate. I have a quiz with 15 questions, but what is weird is that if I test the quiz and get 6 mistake which means 9 right it gives a score of 53%. Base on my math calculation it should be 60%. Each question is rated - score by question and all are graded at 1 for the right answer (see attachment).
How do I find our how the rating is actually calculated and correct it.
