This is an English medium book from RBD Publication by Khan Sir (Bihar Kesari) — Pocket GK, a compact general knowledge volume for competitive examinations across India. The entire book is written in English in the Roman script; candidates preparing in Hindi should look for the Hindi medium edition, as this is the English version of the title. The pocket format is the whole proposition, and it is worth being clear about what it is for. This is not a book to sit down and study; it is a book to carry. General knowledge is the one section of a competitive paper that improves from repetition in short bursts more reliably than from long sessions, because it is pure recall — a fact is either retrievable or it is not, and retrievability comes from encountering the same fact many times rather than from reading it once carefully. The twenty minutes on a bus, the queue at an office, the wait before a class: those add up to more GK revision in a month than most candidates manage at their desk, and only a book small enough to be in a pocket captures them. The content spans the standard static and general awareness ground that recurs across almost every recruitment paper in the country — history, geography, polity, economy, general science, sports, awards, books and authors, important days and organisations. That commonality is precisely why a single compact GK volume is worth owning regardless of which examinations a candidate is targeting: the syllabuses differ in depth, but the static core is largely shared. It is a revision and retention title, best used alongside a fuller general studies book and current affairs preparation.
