Absolutely. If you do not successfully meet the minimum score, you can retake the exam as many times as you want. Most final exams require a 70%. (CA Reg Review requires 90%)
Once you submit your exam for grading, you will be shown the score you earned, and the question numbers you answered incorrectly. Please note, this is the only time you are shown the incorrectly answered question numbers and you are not shown the correct answers.
