"Create tests, exams, and teaching material in minutes" so says the cover of this CD and it is that simple. You first search for questions by type and or topic and the program will then allow you to select a variety of questions and print a test, or an assignment. It will also indicate the time allotted by the IB for each question and it will print a mark scheme as well. It is available for biology and a variety of other subjects. Link to store.
