Actual bundled records, not a target or estimated total.
379 structurally eligible bundled questions · 26 empty chapters · 70 chapters with fewer than 50 questions
This app currently has no persistent question collection or question-import backend. Its existing bundled records are shipped with the app, not stored as database rows. No PYQs have been source-verified. Structural checks reject malformed records, repeated prompts and repeated IDs within a chapter; they do not independently prove scientific correctness, difficulty or official syllabus alignment. Counts below are NOT database counts or a claim of 1,500 validated questions per subject.
The current syllabus catalogue is not certified against the official 2026 Main and Advanced syllabi; check the official documents before relying on this chapter list.
