There are couple of ways to become an Army doctor in the Indian Army. One is through studying MBBS in AFMC. Here you have to appear for NEET and appear for its Admission process which consists of TOELR, PAT and Interview. And to be eligible for NEET, you should have completed your 12th, passed in all subjects and secure a minimum aggregate of 50% in Physics, Chemistry and Biology. It is 50% for General Category, 45% for PWD and 40% for OBC,SC,ST. Now if you belong to OBC Category, the Category you belong to should be also listed in the Central OBC list. Or else you will be considered as General Category and so you have to secure a minimum aggregate of 50% in Physics, Chemistry and Biology. This 50% is inclusive of the Theory and Practical marks scored in Physics, Chemistry and Biology collectively. You needn't score 50% in Physics, 50% in Chemistry and 50% in Biology separately. You need an aggregate of 50% or 40% depending on your Category as an aggregate in Physics, Chemistry and Biology. And along with Physics, Chemistry and Biology, you should also have studied English as one of the core subjects in your 12th.Once you complete MBBS, you can join the Armed Forces as Commissioned Officers in Army, Navy and Air Force. You start with a Monthly pay of Rs.57,800 per month with a designation of Lieutenant. You become a Captain on completion of Internship and start earning Rs.63,100 per month. After 4 years of service as a Captain you are promoted as a Major and then your pay is increased to Rs.71,500 per month. After 7 years of service as Major, you are promoted as Lieutenant Colonel and then your pay becomes Rs.1,24,800 per month. And Lieutenant Colonel to Colonel and Colonel to Brigadier, from Brigadier to Major General  and from Major General to  Lieutenant General is by selection and you take approximately Rs.1,34,000 per month to Rs.2,11,600 per month. The other way is to complete your MBBS from anywhere like ACMS and then apply for SSC. Here as well the pay more or less remains the same.
