Hello @nwi ,
The exam consists of multiple-choice questions, and typically, there are no penalties (negative points) for incorrect answers. In other words, only the questions you answer correctly will count towards your final score.
However, please note the following statement from the Exam Guide, which is worth keeping in mind:
Unscored Content: Exams may include unscored items to gather statistical information for future use. These items are not identified on the form and do not impact your score. Additional time is factored into account for this content.
