Bihar Special Survey Amin study guide
Bihar Special Survey Amin · Work through your exam, one topic at a time.
The Bihar Special Survey Amin credential is a state-level recruitment qualification for survey assistants who work on land measurement, cadastral mapping and field record-keeping under Bihar's revenue and survey administration. It suits candidates with a diploma or certificate background in surveying, civil or rural engineering, or those who have trained in chain, plane table and theodolite work and want a field-based government role. The Bihar Special Survey Amin study guide has 11 sections and about 3,789 words.
01Surveying Fundamentals and Measurement
This domain tests whether you understand what a survey measurement means, how errors enter, and how to convert field values into reliable ground lengths and areas. Expect unit conversions, chain and tape corrections, scale, and precision versus accuracy.
340 words, about 2 min02Survey Instruments and Their Use
This domain covers the instruments an Amin actually handles: tape and chain, ranging rods, cross-staff and optical square, compass, level, theodolite, total station and GPS. Questions test selection, least count, adjustments and bearing conversion.
330 words, about 2 min03Plane Table and Chain Surveying
This domain tests the plane table as a graphical survey method and chain surveying as a linear framework of triangles. Expect methods of plotting, orientation, resection, and the layout of base, check and tie lines.
370 words, about 2 min04Levelling and Contouring
This domain tests height control: benchmark to reduced level, backsight and foresight, rise-and-fall versus height-of-instrument (HI) booking, and how contours represent terrain. Numerical questions are common.
339 words, about 2 min05Theodolite
This domain covers the theodolite's geometry and field use: temporary adjustments, face-left and face-right readings, horizontal and vertical angles, repetition and reiteration, and the errors that averaging removes. Temporary adjustments: setting over the station, levelling with foot screws, focusing the eyepiece and objective, and eliminating parallax.
305 words, about 2 min06Traversing and Computation
This domain tests traverse layout, bearings, latitudes and departures, closing error, adjustment, and area computation. It rewards careful sign conventions more than memorised shortcuts.
349 words, about 2 min07Cadastral Surveying and Land Records
This domain tests village-level revenue surveying and the records an Amin helps prepare or verify: khasra, khata, khatiyan, jamabandi, chauhaddi and the Bihar Bhumi system. Expect map-reading, area-unit conversion and boundary procedure.
369 words, about 2 min08Survey Drawings, Maps and Field Records
This domain tests whether field measurements become a legible, checkable map: scale, plotting, symbols, north direction, legends and the field book. Expect scale conversions and identification of recording errors.
369 words, about 2 min09Mathematics and Basic Computation
This domain tests the arithmetic an Amin uses daily: unit conversion, percentage and ratio, mensuration of plots, triangle solution and coordinate geometry. The exam favours short numerical problems with an exact answer.
327 words, about 2 min10General Knowledge and Bihar-Specific Awareness
This domain checks basic awareness of Bihar's geography, administrative structure, history and land institutions, with an emphasis on facts an Amin encounters in the field. Questions are usually direct, so precise names and dates matter.
355 words, about 2 min11Reasoning and Mental Ability
This domain tests pattern recognition, logical deduction and spatial thinking under time pressure. Typical items are number series, coding-decoding, blood relations, direction sense, syllogism, analogy and seating or ranking puzzles.
