Abstract
A system for making computer software consumable is provided. The software comprises a set of units, each of the units being an interactive activity between the program and the user which can be separately completed from the interactive activities of the other units in the set. The completion of units is monitored by means of a copy-protected region of a recording medium and when all units have been completed, further access to the software is denied. Among the applications for the system are academic tests composed of different subject categories, games having different levels of difficulty, and workbooks having different tasks to be performed.
