Hi Shivam,
The minimum eligibility criteria (educational qualification) for NDA examination is:
Educational Qualifications:

(ii) For Air Force and Naval Wings of National Defence Academy and for the 10+2 Cadet Entry Scheme at the Indian Naval Academy: 12th Class pass of the 10+2 pattern of School Education or equivalent with Physics and Mathematics conducted by a State Education Board or a University.
Candidates who are appearing in the 12th Class under 10+2 Pattern of School Education or equivalent examination can also apply for this examination. These are the conditions to sit for NDA examination in which case diploma might not be the right choice. For more details, please log on to the official website:

Hi Sourabh,
Some institutes are known to offer Diploma courses to 10th passed students though. The quality and validity of such Diploma courses are questionable. Ultimately, such courses are not very useful, when it comes to finding a job using them!
In short, it is better to complete 11th and 12th standards and then pursue a good (and recognized) journalism course.
In India, there are 2 main formats in which journalism courses are available. They are
Bachelors Degree courses
Diploma courses
Degree courses and Diploma courses are the good ones. But for pursuing them, you must complete 10+2 first.
As mentioned before, some institutes do allow 10th passed students to pursue Diploma and certificate courses. But the quality of such courses is not too good. And the credibility and validity of such courses and institutes offering them are questionable too!
It is very important to have a good foundation. That is why I recommend my readers to undergo 10+1 and 10+2 classes. After that, they may study good Degree or Diploma journalism courses.
All the best.
