The Medify software requires a laptop or desktop computer running an up-to-date modern web browser. These include Chrome 51+, Firefox 47+, Safari 9.0+, or Microsoft Edge 13+ (not Internet Explorer).
Some parts of the system such as tutorials may be accessible on smartphones and tablet devices, but the question bank and mock exams will not.
Installing and updating a browser is usually quite safe, easy and straightforward – the browser vendors try hard to make sure everyone can understand them. Their own webpages are the best and most up-to-date place to look for help. You might also find What Is My Browser’s update guide useful.
Contact your system administrator if you can’t change browser yourself.
Or, worst case, use another computer.
