Exam scoring without answering questions

Hi there,I'm having a strange problem in Lectora Enterprise Edition 2008 (v. 9a - 5845).My course consists of a Test with 12 questions and a results page that displays the score. However, when I go through the Test without answering any questions it gives me a score of 76. I am not using any custom code - just the standard lectora question functionality. The questions have all been assigned points (either 1,2 or 3) and none of them have been told to grade each choice as a seperate question. The final question has a button that Submits the test for scoring.If I start answering questions correctly, it seems to add the points for the correct answers to 76 rather than calculating a percentage score.Has anybody encountered anything like this before? Any help would be appreciated. Thanks,Shane
