Hello Mam, I want to make my career in defence. But because of my mistake dates of submission of NDA forms has passed. Please guide me what can I do now or for what should I opt now. I am student of class 12(PCM).

If you are foccued on making career in defence then better wait for the next year's exam and utilize the interim period for preparing so that you pass through in the first attempt itself. Now that you have more time for preparation it could be a blessings in disguise for you. Good luck.
