Question bank is a warehouse of questions that supports
the generation of test or examination. It is also an essential
part of an online course system. The ZOSMAT controls
and evaluates each student’s learning process by using the
test papers and results, which are the basis of question
bank. Only through the tests generated from question
bank, ZOSMAT can get learning information of each student
and record them in student model. In order to generate
one appropriate test easily, question bank must be
organized efficiently.
