Dynamic test: how the questions are selected
Each time student starts a , the Edutizer test engine select a random set of questions from the test's question pool.
Although the selection is random, it does account for the previous student activity. The following questions will be favored:
- questions that student has never answered
- questions that student has answered least recientely
- questions that have least mean result for this student.
Although these factors will be taken into account, the seletion process is still random and does not guarantee that only those kinds of questions will be seleted to the student. Also the seletion process does not outrule that twice the same set of question will be seleted, though the possibility of such occurance is low espessially if the question pool is large.
