This is a two-book combo set of Rajasthan Pariksha 20-20 (राजस्थान परीक्षा-20-20), written by Dr Rajeev 'Lekhak' and published by Disha under its Gyan Sangrah Series. Both books are written entirely in Hindi (Devanagari script), so aspirants preparing in the Hindi medium can study in their own language. Both are the 25th Revised and Enlarged Edition (25वाँ परिष्कृत एवं परिवर्धित संस्करण). Part 1 — Bhugol, Arthvyavastha evam Rajvyavastha covers the geography, economy and polity of Rajasthan (भूगोल, अर्थव्यवस्था एवं राज्यव्यवस्था). Part 2 — Itihas, Kala evam Sanskriti covers the history, art and culture of Rajasthan (इतिहास, कला एवं संस्कृति). Between them the two volumes cover the whole Rajasthan general knowledge syllabus. Both give Advance Level explanations of RPSC and RSSB examination questions from 1992 to February 2026, with standard reference sources cited, and both follow Exam Trend 2026 and the ज्ञान-स्मृति-समझ approach — knowledge, recall and comprehension. Buying the set rather than a single volume matters here because the Rajasthan papers draw on all five subjects, and a candidate who owns only one part is left reading the other from a general GK book at a fraction of the depth. The set is prepared for RAS, PSI, Assistant Professor, JEN, AEN, Computer Anudeshak, Grade I, II and III Teacher, Vanrakshak, LDC, CET and Prayogshala Sahayak examinations.
