The Department of Public Health under the supervision of the Connecticut Medical Examining Board, established pursuant to section 20-8a shall hold examinations not less than twice each year at such places as the department designates. Applicants for licenses to practice medicine or surgery shall be examined in such medical subjects as the department may prescribe, with the advice and consent of the appropriate board, provided each applicant for examination shall be notified concerning the subjects in which he is to be examined. The Commissioner of Public Health, with advice and assistance from each board, shall make such rules and regulations for conducting examinations and for the operation of the board as, from time to time, he deems necessary. Passing scores for examinations shall be established by the department with the consent of the appropriate board. Each applicant for examination shall be examined with respect to the same school of practice in which the applicant was graduated except that an applicant for licensure in homeopathic medicine who is licensed as a physician or meets the requirements in section 20-10 may be examined in other than the school of practice in which such applicant was graduated. Before being admitted to the examination, an applicant shall pay the sum of five hundred sixty-five dollars and an applicant rejected by the department may be reexamined at any subsequent examination, upon payment of the sum of five hundred sixty-five dollars for each appearance.
