(a) The actual preparation of, the administration of, and the grading of, examinations.
(b) The inspection or investigation of licentiates, the manner or method of practice or doing business, or their place of practice or business.
Nothing in this section shall be construed as precluding a public member or a lay member from participating in the formation of policy relating to the scope of the activities set forth in subdivisions (a) and (b) or in the approval, disapproval or modification of the action of its individual members, nor preclude such member from participating as a member of a subcommittee consisting of more than one member of the board in the performance of any duty.
