Compute true bearing from magnetic bearing for five cases using magnetic declination, including east and west declination.

Identify which instrument you would carry for setting out a right angle at a chain line and justify the choice in two lines.

Describe the step-by-step setup of a plane table by radiation, intersection, traversing and resection, and state when each method is preferred.

Explain the three-point problem and solve two numericals using the Lehmann and Bessel methods.

Define orientation in plane table surveying and distinguish between orientation by magnetic needle and by backsight.

Carry out (or simulate on paper) a chain survey of a small closed traverse, recording field book entries in the standard single-line and double-line format.

Detect and correct five typical field book errors such as wrong offsets and missing perpendicular marks.

Distinguish between temporary and permanent adjustments of a dumpy level and list them in correct sequence.

Reduce a complete set of level book readings (backsight, intermediate sight, foresight) by both the height of instrument method and the rise-and-fall method, and verify the arithmetic check.

Compute the collimation error and the effect of curvature and refraction on a 200 m sight, showing the formula and numerical substitution.

Explain the reciprocal levelling procedure and use it to find the true difference of level between two points 300 m apart.

Apply the contour interval rule and describe how to interpolate contours between two spot levels on a drawing.

Describe the parts and adjustments of a transit theodolite and explain the procedure for measuring a horizontal angle by the repetition method.

Compute included angles from a set of observed bearings and check the sum against (2n-4)×90° for a closed traverse.

Calculate latitude and departure for each traverse leg, apply the bowditch rule, and distribute the closing error.

Compute the area of a closed traverse using the coordinate (shoelace) method and verify with the trapezoidal rule.

Explain the uses of a theodolite in setting out curves and state the formula for the length of a simple circular curve.

Explain the purpose of a cadastral survey in Bihar and distinguish khasra, khata, plot number and jamabandi in your own words.

Describe the standard procedure for a khatiyan-based plot survey, including how boundary disputes are recorded in the field book.

List the key Bihar land-record terms (dakhil kharij, mutation, parcha, naksha, amin report) and state in one line what each document contains.

Outline the role and duties of a survey amin during a government cadastral survey, including measurement, sketch and report submission.

Explain how GPS or total station data is integrated with traditional cadastral mapping and note one advantage and one limitation.

Prepare a neat map sheet with title block, north arrow, scale bar, legend and signature panel following standard drafting conventions.

Convert a verbal scale into an RF and draw a diagonal scale that can measure to 1 metre on a 1:500 map.

Compute the area of an irregular plot using the trapezoidal rule, Simpson's rule and the planimeter method, and compare results.

Solve 15 arithmetic and mensuration problems (percentage, ratio, average, area, volume) under timed conditions.

Explain the difference between a map, a plan and a sketch and state which is legally used in land records.

Revise Bihar-specific facts relevant to the exam (districts, divisional headquarters, major rivers, state survey and land-revenue setup) into a one-page revision sheet.

Solve 30 reasoning items (series, analogy, coding-decoding, direction sense, blood relation) in 30 minutes and review every wrong answer.

Take two full-length mock tests under exam timing and record domain-wise scores.

Re-attempt every question missed in earlier weeks' deliverables and log the corrected reasoning for each.

Build a final one-page cheat sheet of the 15 formulas you are most likely to forget.
