A NEET week is easier to trust when the quiz matches the gap.
Generate a chapter-wise quiz when you are still learning the topic. Generate a weak-area quiz when the chapter is familiar and one idea keeps slipping. NuRhoN uses your earlier attempts to suggest which of the two you need.
Biology, and the reason for the option
In biology, mark the option only after the reason is clear. Upload the line of thought, not only the chosen option. If the reason slipped, the next quiz stays on that idea instead of repeating the whole unit.
A wrong option is easier to revise when you can see the sentence that led you there. The quiz is finished when that sentence holds, not when the score looks tidy.
The same loop in every subject
Physics and chemistry follow the same habit. A short quiz shows the concept. A longer set can wait until that concept holds. Numerical items are read for the step that broke, so a calculation error and a concept error do not get the same next quiz.
Switch the solution level if the explanation is too thin or too heavy. Beginner, Medium, and Advanced are there so the walkthrough matches the attempt you just made.
A weekly check that shows the work
Look at the topics you attempted, the error pattern, and the quiz that follows. Accuracy matters, and so does whether the same gap is shrinking.
Parents and students can read that record together: what moved this week, and what still needs another attempt. The plan for the next week stays tied to those gaps.
