Some of the questions are also too similar and look like they're being asked in very slightly different forms to pad out the number of questions available.
For the tests, It also randomly selects a number of questions from the total number available for that category, leaving a few you're not tested on. If you retake the test for that category, it's possible you still won't be asked all those unused questions. An option to try all the questions, or to try the unused questions would be good
