Whilst the Quiz Box is a standalone tool which can be used to conduct personal tests (pre-loaded or generated by the unit), the Test Box has an additional function as it can communicate with a tool such as a PC or a tablet.
This communication is two-way: from the Test Box to the PC and from the PC to the Test Box.
Communications from the Test Box to the PC allow to process the given answers and then score them automatically as well as provide analysis of the types of errors.
Communication from the PC to the Test Box allows new tests, the test function mode, etc. to be loaded into the Test Boxes.
