God I love this picture so much. Everyone who has been through insane curriculum knows this by heart. Apparently faust herself too.
To be honest, studies like these are not safe. They may push stress and sleep deprivation on levels nearing insanity, and may leave scars for rest of the life. Pushing every bit of efficiency out of the students may appear to be cost-effective for the bureau, but it destroys the souls in the process. Machines are meant to work with full power for prolonged times, humans not.
