Information on what you can use in your Blackboard or Moodle digital assessment/exam will be provided by your lecturer or course co-ordinator. Check the examinations information they have provided for your paper in Blackboard or Moodle. The front page of the examination should also list the resources that will be made available.
If you are taking your assessment/exam in ExamSoft/Examplify, your course co-ordinator will specify if calculators are allowed. Check your StudentMail and your course's page on Blackboard for updates.
