hi I was looking for age requirement to apply the fdny exam and i found this... Age requirement EXCEPTIONS: ->Candidates remaining on the eligible list for Firefighter Exam Nos. #6019 and 6506 must not have reached their 36th birthday by the beginning of the application period to be eligible to take this examination. . ->Candidates on Special Military lists for Firefighter Exam No. 2043 in existence on or after July 22, 2009, must not have reached their 36th birthday by the beginning of the application period to be eligible to take this examination. ->All persons who were engaged in military duty as defined in Section 243 of the New York State Military Law (including candidates on the lists noted above) may deduct from their actual age the length of time spent in such military duty up to a maximum deduction of six years but i dont understand the first point, what is Exam 6019 and 6506? thanks
