WBPSC Sub Surveyor Syllabus 2026

WBPSC Sub Surveyor Exam 2026 Overview

The Public Service Commission, West Bengal (WBPSC) conducts the Sub Surveyor examination to recruit technical staff in various engineering and land records departments across West Bengal. This recruitment drives field operations and land mapping initiatives across the state. Aspirants preparing for this examination must align their preparation with the official curriculum outlined by the commission.

WBPSC Sub Surveyor Exam Pattern 2026

The selection process comprises a Written Examination (Preliminary/Screening Test) followed by an Interview or Personality Test. The written exam carries objective multiple-choice questions covering both technical survey engineering and general aptitude.

Detailed Subject-Wise Syllabus

• Compass Surveying: Prismatic compass, surveyor compass, bearings, magnetic declination, local attraction, traverse computation.
• Levelling and Contouring: Types of levels, levelling staff, height of instrument method, rise and fall method, contour lines, characteristics of contours, interpolation.
• Plane Table Surveying: Equipment, methods of plane tabling (radiation, intersection, traversing, resection), two-point and three-point problems.
• Theodolite and Tacheometric Surveying: Transit theodolite adjustments, horizontal and vertical angle measurement, principles of tacheometry, stadia constants.
• Modern Surveying Instruments: Total Station basics, GPS, GIS concepts, digital planimeters, electronic distance measurement (EDM).
• Curves and Earthwork Calculations: Simple circular curves, setting out curves, area computation, trapezoidal and Simpson rules for volume calculation.

2. General Studies

• Indian History: Focus on Indian National Movement, freedom struggle, and cultural heritage of West Bengal.
• Geography: Physical geography of India, river systems, climate, natural resources, with specific reference to West Bengal geography.
• Indian Polity: Indian Constitution, fundamental rights, directive principles, Panchayati Raj institutions, local administration.
• General Science: Everyday physics, chemical reactions, environmental science, biology concepts up to Class 10 standard.
• Current Affairs: National and international events, awards, sports, government schemes, regional updates.

3. Arithmetic and Reasoning

• Arithmetic: Number systems, HCF and LCM, ratio and proportion, percentages, profit and loss, time and work, time and distance, simple and compound interest.
• General Intelligence: Coding-decoding, blood relations, series completion, analogy, direction test, non-verbal reasoning.

Previous Year Cut-Off Trends

Cut-off scores vary based on the difficulty level of the question paper and total applicant numbers. The approximate expected cut-off ranges out of 150 written marks are as follows:

• General (UR): 95 to 105
• OBC-A: 85 to 92
• OBC-B: 88 to 95
• SC: 78 to 86
• ST: 65 to 74

Recommended Books for WBPSC Sub Surveyor

Preparation Strategy for WBPSC Sub Surveyor 2026

Clearing this competitive exam requires structured planning over 4 to 6 months:

• Daily Study Schedule: Dedicate 5 to 6 hours daily, allocating 3.5 hours for technical surveying subjects and 2 hours for general studies and math.
• Prioritise Core Topics: Focus heavily on Chain Surveying, Levelling, Theodolite, and Total Station fundamentals as they carry the maximum technical weightage.
• Formula Revision: Maintain a dedicated notebook for surveying formulas, calculation shortcuts, and field correction techniques.
• Mock Tests: Attempt at least one full-length practice paper per week during the last two months to improve time management and accuracy.

Common Mistakes and How to Avoid Them

• Ignoring General Studies: Many technical candidates neglect Paper II. Ensure consistent revision of general studies and arithmetic to boost overall score.
• Negative Marking Traps: Guesswork often lowers total marks. Attempt only questions where confidence level is high.
• Overlooking Practical Concepts: Surveying questions often test field application. Focus on error correction and instrument reading techniques rather than pure definitions.
