Dear students, as you may have noticed: I was quite dissapointed in the online exam infrastucture and I have decided to do things differently.
We will simply do the exam without the Safe Exam Browser settings in Moodle, such that you can use Excel on your desktop. This means that menu items like Solver, Data Analysis - Regression, keyboard shortcuts etc are available and I don't have to worry about your language settings.
Naturally, you can only have two things open on your computer during the exam: the browser with the Moodle quiz and the excel file that you can download once the exam has started. If you have any other screens or tabs open, this will be penalized as cheating.
If anything about this solution is not clear, please let me know. I am hopeful that this alleviates most if not all of your concerns.
Best, Martijn
