Congratulations on realizing what you want and making a firm commitment. Back in the "day," when I took the exam, the average number of sittings to pass was three. I was average. However, the first two sittings helped me prepare for the final one and I never considered those sittings a waste of time. You learn from everything you do in preparing for the certification exam or any new experience you decide to tackle.
