JSSC JE study guide
JSSC JE · Work through your exam, one topic at a time.
The JSSC Junior Engineer examination is a state-level recruitment test conducted by the Jharkhand Staff Selection Commission to build a merit list for Junior Engineer posts in Civil and Mechanical disciplines within Jharkhand government departments. Candidates typically hold a diploma or degree in Civil or Mechanical Engineering and are seeking a stable public-sector technical role. The JSSC JE study guide has 6 sections and about 1,840 words.
01General Studies for JSSC JE
General Studies in JSSC JE is an objective MCQ block drawn from History, Geography, Indian Polity, Economy, General Science and Current Affairs, and it carries a pronounced Jharkhand flavour. Questions are direct recall rather than analysis, so precision on dates, places and Article numbers decides the score.
324 words, about 2 min02General Mathematics / Quantitative Aptitude
Quantitative Aptitude here is speed arithmetic: number system, percentage, ratio, average, profit and loss, simple and compound interest, time-work, time-speed-distance, mensuration, basic trigonometry and data interpretation. The maths is school-level; marks go to whoever turns a question into one clean equation fastest.
306 words, about 2 min03General Intelligence and Reasoning
This block checks pattern-spotting rather than calculation: series, analogies, classification, coding-decoding, blood relations, direction sense, syllogism, seating and ranking puzzles, clock and calendar, plus non-verbal sets (mirror and water images, paper folding, embedded figures, figure series). Letter positions: A=1 to Z=26; EJOTY (E=5, J=10, O=15, T=20, Y=25) gives quick anchors.
284 words, about 1 min04General Engineering (Common Fundamentals)
General Engineering is shared by Civil and Mechanical candidates, so it stays at first-year fundamentals: units and measurement, force and moment, work-power-energy, simple machines, stress and strain, material properties, basic thermal and fluid ideas, and workshop or drawing basics. SI: force in newton, stress and pressure in pascal; 1 N/mm² = 1 MPa = 10⁶ Pa.
279 words, about 1 min05Civil Engineering Core Subjects
The Civil core paper covers Building Materials, Surveying, Structural Analysis, RCC and Steel Design, Geotechnical Engineering, Hydraulics, Transportation and Environmental Engineering. Expect code-based numbers: grades, permissible stresses, partial safety factors and IRC values.
325 words, about 2 min06Mechanical Engineering Core Subjects
Mechanical core spans Thermodynamics, Fluid Mechanics, Strength of Materials, Theory of Machines, Manufacturing/Production and Industrial Engineering. Numerical questions cluster around efficiency, stress, gear geometry, EOQ and PERT.
