This book from Gyan Vitan is a Hindi medium (हिन्दी माध्यम) title by Kailash Jani, who secured 13th Rank in RAS 2024, covering Vigyan evam Praudyogiki (विज्ञान एवं प्रौद्योगिकी) — science and technology — organised specifically from the RAS examination point of view. This is the second edition, and it is described as NCERT integrated (NCERT समेकित).
The author's credential is unusually direct here. A candidate who ranked 13th in RAS 2024 wrote this having just sat the paper, and the publisher states that most of the questions asked in RAS Mains 2024 came from the first edition of this book. That claim is worth verifying independently, but the underlying logic holds: someone who has recently cleared the examination at a high rank knows what the paper demands better than a compiler working from general science texts.
The scope is set out as five parts — jeev vigyan, paryavaran evam paristhitiki, rasayan vigyan, bhautik vigyan and praudyogiki evam navachar (जीव विज्ञान, पर्यावरण एवं पारिस्थितिकी, रसायन विज्ञान, भौतिक विज्ञान, प्रौद्योगिकी एवं नवाचार). Two things about that list matter. Environment and ecology being treated as a full section rather than an appendix reflects its actual weightage in RAS. And technology and innovation — the section that goes stale fastest — is kept separate rather than being scattered through the science chapters. The NCERT integration addresses the standard problem that NCERT reading is essential but far too time-consuming; here the examinable content is drawn out and arranged for the paper. The book is prepared as useful for UPSC, State PCS, RAS Pre and Mains, SI, Junior Accountant, CET, REET, VDO, Patwar and Police, among other central and state examinations. The whole book is written in Hindi in the Devanagari script.

ज्ञान वितान द्वारा प्रकाशित कैलाश जाणी (RAS 2024 — 13वीं रैंक) की 'विज्ञान एवं प्रौद्योगिकी' का यह द्वितीय संस्करण RAS परीक्षा की दृष्टि से संयोजित तथा NCERT समेकित है। लेखक की योग्यता यहाँ प्रत्यक्ष रूप से प्रासंगिक है — RAS 2024 में 13वीं रैंक प्राप्त अभ्यर्थी द्वारा लिखी गई पुस्तक में यह समझ स्वाभाविक रूप से रहती है कि प्रश्न-पत्र वास्तव में क्या माँगता है; प्रकाशक के अनुसार RAS मुख्य परीक्षा 2024 में पूछे गए अधिकांश प्रश्न इसी पुस्तक के प्रथम संस्करण से थे। पुस्तक पाँच भागों में विभाजित है — जीव विज्ञान, पर्यावरण एवं पारिस्थितिकी, रसायन विज्ञान, भौतिक विज्ञान तथा प्रौद्योगिकी एवं नवाचार। इनमें दो बातें विशेष उल्लेखनीय हैं: पर्यावरण एवं पारिस्थितिकी को पूर्ण खंड के रूप में रखा गया है, जो RAS में इसके वास्तविक भारांक के अनुरूप है; तथा प्रौद्योगिकी एवं नवाचार — जो सबसे शीघ्र पुराना होने वाला भाग है — पृथक रखा गया है। NCERT समेकित होने से NCERT पढ़ने में लगने वाला समय बचता है। यह UPSC, State PCS, RAS प्री एवं मुख्य, SI, कनिष्ठ लेखाकार, CET, REET, VDO, पटवार तथा पुलिस सहित समस्त परीक्षाओं हेतु उपयोगी है। ध्यान दें: यह पुस्तक पूर्णतः हिन्दी भाषा एवं देवनागरी लिपि में है।
