The series 66 Is a challenging exam. You will find that the questions asked on the exam tend to be more complicated than questions on other exams . The most important thing you can do is to identify what the question is asking you. Simply because information appears in the question does not mean that it is important to the answer. Information often appears in a question simply as a distracter. Identifying the key information and determining what the question is asking will help you navigate the question and find the correct answer.
Remember to become fully registered you must pass the series 7 as the co requisite to the series 66. You may take either exam first but the series 7 must be passed to conduct business with investors.
