Hello Seniors, i have doubts regarding following matters, if any one has the answer, please share with me.. I am just MBBS. i heard if i join Central mdical services, after a service of 3 or 5 years, there would be some kind of reservatin in PG seats. is it realy so???

and about Army medical servies, i know, after permanent commission,  they make us do PG without any enterance or anything, the age of the candidate on the time of permanent commision shouldnt be more than 30 years. but what if some one not eligible for permament because of age, but with same years of service as that of a comissioned officer, is the candidate still eligible for PG in army college or hospitals..
