The National Defence Academy & Naval Academy (NDA & NA) syllabus on Koshish is split into two lists: subjects with a verified question bank you can practise now, and subjects on the syllabus whose banks are still being built. The split is rendered from the live catalogue, so a subject is never shown as ready when it is not.
Each of these has at least one servable question, so the practice screen is never empty for them. "Verified" here means a question has passed our review pipeline and can be served in the app right now; anything shown as verified is counted from that servable set.
