Interviews - Introduction
The interview portion of the guide is meant to give you some insight into the test experiences of others. You will notice that most of the interview participants had widely different study methods and approaches, which was reflected in their scores.
From the interviews it is clear that each candidate's aptitude toward the securities markets and their study habits had a direct correlation to their exam performance. Not surprisingly, those who were more investment focused in college seemed to fare better on the exam. What's more, those simply obtaining their Series 63 as a business requirement (and weren't passionate about the financial markets) seemed to have more trouble with the exam.
In short, if you are passionate about the markets, and/or have already studied for an exam like the Series 6 or 7, you will most likely have a better chance of passing, with less study time. However, this does not give you a green light to neglect studying the material at hand. You must still put in the time. If you are not receiving 85 or better on all of your practice exams, you will probably fail!
Exam Tips and Tricks
The best advice (mentioned the second time in the study guide) is to take all the practice exams at least TWICE. If you are not acing the practice exams, you may not have a firm grasp on the material.
