Thanks Allison
I have just built a course with the opportunity to go straight to the final assessment. Learners were provided with ONE attempt. If they failed the 80+% pass rate (module-dependent), they were directed back to go through the entire module following which, they were allowed 3 attempts with random question and answer placement. It worked well but you always have the possibility that the questions failed are critical process questions so I a looking at modifying this in version 2 to use a pre-assessment and branching to provide a tailored refresher module - summarise the critical information that the user has proven they understand and then provide the full detail and post-module testing for the topics they did not understand. We will see how I go.
