P300 is a special evoked potential which tests conscious processing. The idea is to smuggle surprising stimuli between boring stimuli. The EEG is only averaged at the moment a surprising stimulus is displayed. This means it’s far slower to record than the normal evoked potential. On the plus side it’s stronger than the passive one.
