Career options just after my class 12

Name: Atul

Q: Sir, i am a student of class 12 with PCM background. my father is suffering from a deadly disease, unfortunately i have to drop this year as he is the only earner in a family of 6. Dear sir my ultimate aim is to be an IAS officer but before that i will need a graduate or some equivalent degree. i had planned to appear in NDA exam this year but unfortunately i will not be eligible for it as i have dropped this year.next year too i will not be able to sit in NDA because of age restrictions.

As my financial background is very weak i could not afford any coaching for competitive exams like IIT JEE or AIEEE.

Sir i am very much inclined in joining Indian air force in flying branch just after my class 12 so that i will be able to support my family before heading for civil services.is there any way to do that leaving NDA?? i also want to know all about SCRA exam. whether i will be able to join air force after doing SCRA? what are the other career options for me seeing all my conditions?
