Yes, student from each stream can appear for NDA exam. But you will only be eligible for Army if you are not having Maths &Physics in 12th class.

Yes, of course you can clear the NDA exam by skipping integration chapter, but you need to be well prepared in rest of the chapters further you need to work out as much as possible. Generally, integration doesn't have higher weightage. Since you are leaving this then you need to be thorough in equations, Probability calculus and rest of the chapters as they carry higher weightage. My suggestion is that it's better if you have a basic knowledge on integration.

Hello Student, Sometimes, there are technical glitches in the website. Hence, the application payment status is not visible to you but as soon as the glitch is resolved you will be able to SEE that your payment is done. You can wait for some days but if the issue is persisting then you should contact the college administrative department and ask them to solve the query regarding your payment. You must show your bank passbook and fee deposit details to the administrative department in order to be on safer side.
