Perfection Book — Comprehensive Guide, written by Nimisha Bansal and published by Prep Duniya Publishers, is an English-medium practice book for the English section of banking, staff selection and defence examinations. The complete book is written in English (Roman script) and contains no Hindi content. The book gives 51 practice sets carrying more than 1000 questions, covering both Pre and Mains levels, with new pattern questions and detailed explanations throughout. Miscellaneous questions are included alongside the set-wise practice, so an aspirant works across question types rather than only the ones a particular exam favours. Practice with explanations is what converts grammar knowledge into marks, since most errors in the English section come from applying a rule wrongly rather than not knowing it. It is prepared for SBI, IBPS, RBI, SSC CGL, CHSL, Stenographer, CPO, MTS, CDS, CAT and NDA examinations, and all other competitive examinations with an English section.
