According to the standard, this function is off. If necessary, it can be included on request in the technical service.
This function forcibly completes the test if the user has minimized the application or received an incoming call. To avoid cheating or peeping into the materials.
Since tests can often be of great importance and provide us with only 1 attempt (which the administrator has configured), and they can call us at any time, only a few of all companies use this function.
