This is standard procedure for many medical school exams during COVID. Examsoft locks down your primary device, and you have a secondary device (smartphone/other laptop) pointed at you throughout the exam with a live video stream to the proctor. Each student does a 360 of their workspace prior to beginning the exam, and they are recorded throughout.

From the article: "To hinder online cheating, Geisel requires students to turn on ExamSoft — a separate tool that prevents them from looking up study materials during tests — on the laptop or tablet on which they take exams. The school also requires students to keep a backup device nearby. The faculty member’s report made administrators concerned that some students may have used their backup device to look at course material on Canvas while taking tests on their primary device."

I'm not sure what's going on here. The med school I'm affiliated with has students running the live video stream to the proctor through the secondary device. I guess Dartmouth wasn't doing that, but was having students keep it nearby only as a communication device in case WiFi went down or something?

Either way, the fact that they've taken students in one of the most competitive and stressful post-graduate programs in the country, told them to sit at home for a year-and-a-half and teach themselves medicine, and subjected them to a scored STEP 1 the year before it goes pass/fail is beyond fucked.
