Does anyone know how to sign up for the written exam? I have done the initial Primary certification step on the ABA website and paid the $550 fee. It now says my status is "validate" and am permitted to sit for the exam. It states "NOTE: A $400.00 Part 1 (written) examination fee is due when candidates accept an anesthesiology certification examination opportunity." No where on the website can I figure out how to sign up for the exam. This is all too confusing. Thank you.
