we join x or y group to become tha doctor in Indian airforce base
For a post of Medical assistant in Indian airforce you have to join Y group and have to give the exams according to Y group which will contain two papers(Online mode) English and RAGA(Reasoning & General Awareness ) and after qualifying this you will be called for physical fitness test and medical examination.
other way to be a doctor in Airforce is by
1.applying for AFMC(Armed Forces Military College ) right after class 12
2.applying for Combined Medical Services Exam after completing your MBBS.
Hope this helps.
