Yes! We are *constantly* revising the content of our courses because scientific understanding is always evolving and expanding. The changes in our courses may be minor or more significant. At the same time, we give our students flexibility on how they pace their semesters and if/when they wish to pursue the AFMC certification. This means that a student may have initially experienced a given course 6, 12, 18, or even more months prior to their AFMC exam preparation. Our AFMC exam content also evolves over time to reflect current scientific understanding and SAFM Scientific Review Board input. The AFMC exams will always be based on the now-current version of all the required courses for that exam level. This is why we guide AFMC exam candidates through a six-week study and preparation period prior to the exam window. During that preparation process, it's Very important that students re-experience all of the main course webinars (as we guide them to do, week-by-week) based on the content that is currently posted on the course pages in their student account (and not prior, earlier versions they may have downloaded).
