I am using Jean-Michel's packaging of the 1.6 essay question in 1.5.2. At the completion of a quiz with essay questions the score is currently calculated using all the quesitons, essay questions contributing 0 until graded. This means a student with half essay questions will see a score of 50% when the quiz is completed, with no indication that there are any ungraded questions. The score should be calculated using only questions that have been graded, and the display to the student should also show how many questions remain ungraded. At the very least the display should indicate to the student that there are xx ungraded questions.
