This is a part of my suggestion for the Advisory Board of IBO, held in Prague Yesterday:
...I would like to emphasize once again upon the number vs. quality of IBO test questions. My suggestion is to decrease the number of multiple-choice type A questions, until their defined quota i.e. 25% of the theoretical task. This will provide enough space to increase the number of type B questions.
To improve the quality of IBO, I suggest limiting the number of theoretical part at 50. This will provide enough time to improve the procedures of judging and translating during the sessions...
