I have tried the exam mode several times, however, it seems that it will stop at the steps to rise up the plunge freezer. When I click the 'start procedure', the plunge freezer does not rise. I think the program have already detect it as in the error report, there is no reporting that I didn't click (if I indeed didn't click, it will show that I do not click it) Moreover, maybe it is better if we can scroll down the error report.
Also, sometimes it will turn into black screen if I click for more times.
