These questions are free to read. The app is the paid part, and it covers the whole exam rather
than stopping at Prelims: 83 Prelims topics, 34 Mains topics across 5 papers, the
interview, and 19 Bihar-specific topics — 94 chapters in reading order, each with a brief
on how the examiner asks it. ₹199 for a month, or ₹499 until your attempt is done — which is the one
to take if your exam is close.
