Hello aspirant,

YEs, you can apply for NDA (National defense Academy ) exam in 2024 because you will be then 19 years of age which will make you eligible for the NDA Exam.

The lower age limit says candidates should be 16 years during the commencement of course while the upper age limit to appear for NDA exam says candidates must be 19 years during the commencement of course i.e. candidates should be between the age of 16.5 years and 19.5 years to be eligible for the exam.

So, for the other part of your question - It is your choice to appear for NDA 1 or NDA 2. You can give only 1 or both NDA exam. But, If you pass the NDA 1 exam then it is not compulsory to fill the NDA 2 form . NDA is an exam which is conducted by the UPSC twice in a year.
