As a teacher in ChromEx you can add external resources that the student will get access to during their exam. The resources that are available can securely be made available to the student without any risk of cheating.
Why are some resources only available when an exam is limited to Chrome OS Kiosk mode?
Chrome OS gives more powerful tools to lock down external resources than e.g. SafeExamBrowser and therefore we have to limit some resources for Chrome OS kiosk mode.
See this Google Sheet for information about which resources are available in each platform: https://docs.google.com/spreadsheets/d/1L455BM3iZgPArWdVmgxxE4ku2kGL1AN5_y2v50VDDQI/edit#gid=0
