We have been listening to more of your feature request adding some more minor features to Brainsbuilder/TestBranch.
We have added the ability to hide or display the finish link that is displayed at the end of the assessment depending on the if the person taking the assessment has passed or failed the assessment. Or the finish link can always be shown or hidden.
For private student assessments we have added the ability to block a person retaking an assessment if they have already passed. Previously there was only the ability to set a fixed amount of retakes.
Please keep your suggestions coming.
