It turns out completely destroying iPads is reasonably hard to do just by dropping it. However, since we can never be too sure, EOSCE does periodic data backups over WiFi in regular 1 minute intervals. Backed up data can then be restored to a new device by the examination administrator. Examiners are advised to take notes on paper during this time. Data that could not be backed up can still be restored from iPads when connecting them to iTunes (this works even if the iPad’s display is broken).
