How does the CIA exam get graded?
The CIA exam is graded on a scaled system. This means that candidates are not given a passing percentage, they just need to earn a certain amount of points in order to pass. The passing score is 600 on a scale from 250-750, and points are earned by answering questions correctly. No points are deducted for incorrect answers, so answer each question with an educated guess and never leave a question unanswered.
If you score in the high 500s, then you probably just need some fine tuning on various exam topics. If you score lower than 500, you should consider revising your study plan and commit more time to learning the fundamental concepts.
How many points your questions are worth is dependent on the difficulty of your exam and is not disclosed to the candidate. The IIA determines the difficulty of questions and your overall exam by inserting non-graded pretest questions into every exam.
