Does Respondus support "calculated" or "algorithmic" questions?
Posted by Respondus Support

Respondus 4 supports the creating or editing of "calculated" or "arithmetic" questions for Blackboard Learn 9.1, D2L Brightspace, and Moodle. Respondus can also retrieve calculated questions the same LMSs. Once downloaded, calculated questions can be edited, moved, copied, deleted, or resubmitted to the LMS.

Respondus offers a similar "algorithmic" question type for Pearson Learning Studio (eCollege) and IMS QTI users. The primary difference is how the algorithmic question appears to the student during the online exam. Algorithmic questions once published cannot be retrieved back into Respondus 4.0. Instructure Canvas is not supported at this time.
 
The Respondus Help and the User Guide has further details on the calculated/algorithmic question type.
