Hello Student

After joining IAF training.you can apply for study leave to appear for the third and final examination for your graduation. On the  other  hand it will be better for you to complete your graduation and then join IAF or Army or Navy whatever you can avail of the opportunity or whatever  will be your interest for. This is because the reviews information says that after servicing of 8 to 10 years you will get the promotion in IAF. The salary will be hiked at that point but the career prospect will be not so bright.  But if you complete your graduation and join in MBA course with CAT GMAT Xat exams your career will be  better than IAF services.

Hope this helps.
