Key takeaways
- Students submit immediately; answers stay hidden.
- You decide exactly when the key and results go live.
- Publishing per batch keeps staggered tests fair.
- Question reports stay in threads tied to the right student.
When a batch takes the same test at slightly different times — some in class, some at home that evening — a single leaked answer key can undermine the whole exercise. Answer-key control exists to prevent exactly that.
Submit now, reveal later
In Nindo, a student can complete and submit a test the moment they're done. What stays hidden is the detailed answers, explanations, and scoring. The institute holds the key until it chooses to publish — so a student who finishes early can't pass answers to one who hasn't started.
Why it matters for a batch
- Staggered attempts stay fair: early finishers don't gain an advantage.
- You can run the same paper across multiple sessions or batches.
- Results land as a deliberate event, not a leak, so you can pair them with a review session.
Handle disputes cleanly
Even a careful paper gets the occasional challenge. Students can report an issue on a specific question, and those reports stay in structured threads tied to the right student and question — not buried in a chat group. You resolve them with full context, and the question bank gets better over time.
Control over the key is a small feature with an outsized effect: it's what lets an institute trust its own mock tests, and what turns results day into a lesson instead of an argument.
