Government & Defence Entrance Exam

Hi Pankhuri,
Even though the exam to be undertaken is popularly known as IAS exam, it is officially called UPSC Civil Services Exam. The UPSC CSE consists of 3 stages Prelims, Mains, and Interview. Getting into Indian Administrative Service is not easy considering the competition involved, but not impossible for a candidate with right attitude and approach.
UPSC (Union Public Service Commission) is the government agency responsible for selecting the right candidates for this service. Every year only around 1000 candidates are selected for all the 24 services combined. The number of candidates who applied for UPSC Civil Service Exam was about 9 lakh in 2015, out of which around 4.5 lakh candidates appeared on the exam day.
This exam is widely considered as the toughest exam in the world, considering the exam duration (extends 1 year), depth of the syllabus and the competition involved. The first stage of the exam Preliminary (objective) is usually conducted around June, while the second stage, Mains (written), is conducted around October. Those who clear Mains will have to face interview/personality test during the March-May period. The final result
usually comes in June.
A disciplined and focused mind with a passion for learning and reading is the basic trait of all successful candidates. The UPSC Civil Services exam is more a test of the analytic and presentation skills along with knowledge gained by the candidate rather than a test which checks candidates mathematical or verbal skills. To clear IAS, we feel two entities as essential:
Right guidance for prelims and mains.
Right study materials and books.

Eligibility for Indian Navy and Air Force in NDA is:
Those seeking for Indian Navy and Air Force must have passed their 12th/appearing from a recognized board or University with Physics and Mathematics as a compulsory subject.
So as per the rules, for Nav/IAF, you need to join science stream but for Army there is no compulsion on the stream. So, you can join NDA but you would have the option of Army only.
