Hello Sir

As you are a medical student in your 10+2 high school , you can join the Indian army as a medical officer (Docter) .

For that you need to do your MBBS from any reputed university and then join the Army .

OR you can do your MBBS from AFMC (Army Forces Medical College) from where you can directly join the army

as a medical officer .

Although , if you DONT want to join as a docter , then it is compulsory that you have Physics and Maths as subjects in your 10+2 , if you had these two subjects in your 12 th class boards then you can apply for NDA or the TES entry.
