The fee of $300 (plus applicable taxes) gives you all the paperwork you need to study for the exam. Challenging the exam requires an additional fee of $200 unless it is done at an Academy then it is included in the Academy fee. You have three years from acceptance on this program to complete all three phases. If not completed by then you can apply to re-register for an additional fee of $300 and if granted, you will have an additional three years. There will be no add-ons after this time. A mentor will be assigned to you to help you through the process. You will need them most in stage 2 & 3. (Therefore Associate Members will not have a Mentor assigned)
Good Luck on your journey, work hard, the rewards come after the achievement.
