SCORM

Hi,

I am using moodle 1.9.5+ , scorm 1.2 and adobe captivate to create courses.
Number of user attempts it set to 1, grading method set to highest grade.

When user enter the course for the first time, it lets him take the course and he passes the exam with a certificate ( > 70%). When he visits the same course again it takes him to the last page " Score report slide of the course". When he tries to visit the course again its letting him take the course again and also changing the score to "0" on grade book on the first slide of the course of 2nd review attempt.

I want to lock or make it a review mode once he passes the course and not let it change any previous grades.

Can any one suggest me of an idea?

Thanks,
