A method of administering a high stakes test includes providing a proctor device and providing a plurality of response devices, with each response device being associated with one of a plurality of subjects. The power supply generates a first high voltage, short duration output across the first and second electrodes during a first time interval to ionize air within the air gap to thereby reduce the high impedance across the air gap to a lower impedance to enable current flow across the air gap at a lower voltage level. In addition, since the Internet service servers connected through the digital network and the Internet service server proxy connected to the Internet have the same protocol layer, so that the type of the service and information can be shared by them and its application program can be easily fabricated. In some embodiments the player is configured to generate auditory signals to indicate to the user that it is tuned to a particular preset station. Each LCD device includes an LCD panel, and a drive circuit controlling a display of the LCD pane The drive circuit includes an adjusting equipment storing a display parameter, and the display parameters of the adjusting equipments of at least two LCD devices of the plurality of LCD devices are different.
