Just interested in trying to understand the algorithm
Sure. Join about 1.5 million other users who have been trying to understand the algorithm for the last 20 years because it is not public.
We know that because of the adaptive nature of the test, the score doesn’t exactly depend on the number of correct answers.
For example, sometimes people make one mistake and get Q 82 (I’d rather extreme case but nevertheless). Sometimes they make three mistakes and get Q 85.
There are many variables involved including experimental questions which do not count towards your score, as well as the overall question bank difficulty, but the bottom line is that the best way to score high is to try to answer all questions and to answer as many of the hard questions correctly as possible. Some extent the score does depend on the correct answers but it doesn’t correlate with it very linearly.
At this point, you should probably book a test.
