Electrical Engineering students at the University of Twente performed a "double examination" on 10 June. Their paper based answers will be compared with digital answers. This pilot explores the potential of digital testing, evaluating the scoring quality as well as security issues. Students are involved in the security analysis of both technical issues and use scenarios. More pilots on the edge of mathematics and engineering will take place as a result of collaboration between 4TU.AMI (mathematics) and the Centre for Engineering Education.
