If yоu wоuld prefer tо wаtch the video version of this KEY insteаd of reаding the written version, see the video below. Viewing this video is optional. You must still submit ALL of the reflection questions at the end to receive credit for Brain Training. You are still welcome to read the written key instead of the video if you prefer that format.   NOTE: The video keys are still in the process of being fully updated (based on new guidelines, new recommendations, etc.). In the meantime, we have posted the video key created by last year's APPE student (Dr. Riley Carroll) for each IESA exercise. We will list any relevant updates in the text that appears before each video. Updates since last year's IESA 1 Video Key (below): None for this case
