If you don't understand, call the Board office. Take pains in preparing your CE report. Report no less than required number of hours. If you have lots to choose from, select those for which you have good documentation and which clearly meet standards. Audit requires you to document everything you report.
Audit is a review of printed materials.
Your documents speak for you. Other forms of input will not be considered by the auditor. Submit by deadline. This takes a long time. Persons failing the audit, may be allowed to submit additional materials to assist the Board in determining if discipline should be proposed.
