No agency in the department shall, on the basis of an applicant’s failure to successfully complete prior examinations, impose any additional limitations, restrictions, prerequisites, or requirements on any applicant who wishes to participate in subsequent examinations except that any examining agency which allows an applicant conditional credit for successfully completing a divisible part of an examination may require that an applicant be reexamined in those parts successfully completed if such applicant has not successfully completed all parts of the examination within a required period of time established by the examining agency. Nothing in this section, however, requires the exemption of such applicant from the regular fees and requirements normally associated with examinations.
