Computer Aided Assessment (also but less commonly referred to as e-Assessment), ranging from automated multiple-choice tests to more sophisticated systems is becoming increasingly common.
Computer-Based Testing (CBT), also called e-Exam, computerized testing and Computer-Administered Testing, is a method of administering a test in which the responses are electronically recorded and assessed.
