3.  No one shall be entitled to be certified for appointment whose standing upon a just grading in the general examination shall be less than 65 per cent of complete proficiency in the first three subjects mentioned in this rule, and that measure of proficiency shall be deemed adequate.

4.  For places in which a lower degree of education will suffice the Commission may limit the examinations to less than the five subjects above mentioned; but no person shall be certified for appointment under this clause whose grading shall be less than an average of 65 per cent on such of the first three subjects or parts thereof as the examination may embrace.

5.  The Commission may also order examinations upon other subjects of a technical or special character to test the capacity which may be needed in any part of the classified service which requires peculiar information or skill.  Examinations hereunder may be competitive or noncompetitive, and the maximum limitations of age contained in the twelfth rule shall not apply to applicants for the same.  The application for and notice of these special examinations, the records thereof, and the certification of those found competent shall be such as the Commission may provide for.  After consulting the head of any Department or office the Commission may from time to time designate, subject to the approval of the President, the positions therein for which applicants may be required to pass the special examination.

  RULE XI.

1.  Every application, in order to entitle the applicant to appear for examination or to be examined, must state under oath the facts on the following subjects:  (1) Full name, residence, and post-office address; (2) citizenship; (3) age; (4) place of birth; (5) health and physical capacity for the public service; (6) right of preference by reason of military or naval service; (7) previous employment in the public service; (8) business or employment and residence for the previous five years; (9) education.  Such other information shall be furnished as the Commission may reasonably require touching the applicant’s fitness for the public service.  The applicant must also state the number of members of his family in the public service and where employed, and must also assert that he is not disqualified under section 8 of the civil-service act, which is as follows: 

  “That no person habitually using intoxicating beverages to excess shall
  be appointed to or retained in any office, appointment, or employment to
  which the provisions of this act are applicable.”

  No person dismissed from the public service for misconduct shall be
  admitted to examination within two years thereafter.
