Why can I answer a few questions incorrectly and still pass the exam?

Uxcel exams utilize computerized adaptive testing. This means each question you encounter depends on your previous responses. If you answer many questions correctly, you will face increasingly advanced ones. Therefore, even if you answer some advanced questions incorrectly, you can still achieve a high score. On the other hand, consistently answering introductory questions correctly will likely result in a lower score than suggested by the total number of correct answers.
