SSC Junior Engineer Examination (JE): Civil, Mechanical, Electrical

Paper I blueprint, topic priority matrix, formula and fact sheets and a practice arena for SSC JE, a central government engineering job that diploma holders can apply for, not just B.Tech graduates.

Staff Selection Commission (SSC)30 practice MCQs with solutionsMarking: +1 / -0.25 / 0

Stages: Paper I (CBT, qualifying) → Paper II (CBT, decides merit) → document verification
Paper I: 200 MCQs, 200 marks: Reasoning 50 + General Awareness 50 + your branch's technical part 100 (Civil, Electrical or Mechanical)
Paper I time: 2 hours (2 hours 40 minutes for eligible scribe candidates); no sectional time limit stated in the notice
Paper II: Technical paper of your branch only: 100 MCQs, 300 marks (3 each), 1 mark cut per wrong answer, 2 hours
On-screen aids: Scientific calculator on screen; IS 456:2000 table and steam table under 'Useful Data'; physical calculators and tables not allowed
Language: English and Hindi, objective MCQs only
2026 cycle: Notice released 2 Sept 2026; Paper I tentatively Oct/Nov 2026, Paper II tentatively Dec 2026

This is the Paper I scheme: 1 mark per question and 0.25 deducted per wrong answer in all three parts. Per the 2026 notice Paper I is qualifying: it shortlists for Paper II, and final merit is drawn up from normalised Paper II marks only. Paper II gives 3 marks per question and cuts 1 mark per wrong answer. Scores from different shifts are normalised, and Mechanical and Electrical scores are also normalised against each other. Check the notice on ssc.gov.in for the minimum qualifying marks in Paper I.

How to Crack: Strategic Blueprint

Pick where you are. Each plan is built around past papers, a formula diary and honest mock analysis.

Diploma holders are eligible for many JE posts (for example CPWD JE Civil and JE Electrical ask for a diploma), so start during the diploma and use your branch subjects as the base for both papers.

1Check the post-wise qualification table in the notice: some departments accept a diploma alone, others want a degree or a diploma plus experience, so list the posts you can actually apply for.
2Revise your diploma notes subject by subject in the order of the priority matrix: building materials, RCC and soil mechanics for Civil; machines and basics for Electrical; thermal and fluid machinery for Mechanical.
3Solve SSC JE previous papers topic-wise right after each subject; JE questions repeat concepts far more than they repeat wording.
4Give reasoning 45 minutes a day from the start; it is the easiest 50 marks in Paper I for most engineering students.
5From three months before Paper I, write one full 200-question mock a week, then add Paper II-style 3-mark practice for your branch.

Topper-grade short notes

One-page subject sheets

For each technical subject, fit the formulas, IS code values, standard tests and two typical question types on one page. In the last month these sheets are all you revise.

IS code and standard values diary

A separate small notebook for numbers SSC loves: setting times, cover values, xu,max/d, slip values, standard constants, IRC values. Read it for 10 minutes daily; these are 1-mark recall questions.

GA one-liners with a 1-7-30 cycle

Write every static fact as a one-liner ('Battle of Plassey: 1757', 'Tenth Schedule: anti-defection'). Revise after 1, 7 and 30 days; GA is pure memory and fades fast without spaced revision.

Error notebook by part

Keep three sections: Reasoning, GA, Technical. For each wrong or guessed question write the concept in one line and the trap you fell for. Re-solve the technical ones every two weeks.

Ideal self-study day

6:00 - 6:30IS code and standard values diary, or GA one-liners
6:30 - 8:30Deep work: one technical subject from the priority matrix
8:30 - 9:00Breakfast and a short walk
9:00 - 13:00College, diploma classes or work
14:00 - 15:00PYQs of today's technical topic, timed (about 36 seconds each)
15:00 - 15:45Reasoning: 25 mixed questions, verbal plus non-verbal
17:30 - 18:15General Awareness: current affairs plus one static GK subject
18:15 - 19:30Second technical subject: theory revision and objective questions
20:30 - 21:15Error notebook: log and re-solve today's mistakes

Topic Weightage & Do-or-Die Matrix

Estimates from the SSC JE 2026 syllabus topics, shift-wise SSC JE 2025 Paper I reviews by Adda247 and Testbook (which describe question types but give no exact counts) and the usual SSC reasoning pattern; SSC does not publish weightage.

Must-DoMediumLow priority

Must-do topics carry roughly 124 of 200 marks (counting one branch paper). Get the must-do topics accurate and a safe Paper I score is within reach, and the same technical base carries straight into Paper II, where your rank is decided.

SSC does not publish topic weightage, and SSC does not release questions publicly; these are estimates from candidate-reported shift analyses and change from shift to shift.

🔴 Must-Do · High weightage

Analogy (number, letter, word)4-6 QsNamed first in the syllabus and asked in every shift in several forms.
Classification (odd one out)4-6 QsQuick number, letter and word groups; very scoring with practice.
Series (number, letter, alphanumeric)4-6 QsStandard patterns (squares, cubes, x2+1, alternating) repeat constantly.
Coding-Decoding3-5 QsLetter-shift, reverse and number coding; fast once the shift rule is seen.
Mirror/water image, paper folding and embedded figures4-6 QsThe syllabus stresses space visualisation; non-verbal items fill a large share of the section.

🟡 Medium · Scoring

Figure series, completion and counting figures3-4 QsCounting triangles and figure patterns appear in most shifts.
Mathematical operations and symbol substitution2-4 QsInterchange-the-signs questions test BODMAS under pressure.
Statement-conclusion and syllogism2-4 Qs2025 shift reviews mention statement-based questions in several shifts.
Blood relations2-3 QsPointing and coded-relation questions; draw a family tree every time.
Missing number and matrix2-3 QsRow and column arithmetic patterns; overlaps with arithmetical reasoning.
Order, ranking and seating arrangement2-3 QsShort linear or circular arrangements and position-from-ends.
Direction and distance1-3 QsSimple walks; answers often need Pythagoras.
Venn diagrams1-2 QsRelationship-of-classes questions from the 'relationship concepts' line of the syllabus.

🟢 Low priority · Lengthy

Number Series Patterns

Squares/cubes1, 4, 9, 16... and 1, 8, 27, 64...
Doubling plus one3, 7, 15, 31, 63 (x2 + 1)
DifferencesCheck 1st differences, then 2nd differences
AlternatingTwo series mixed: odd terms and even terms separately
Primes2, 3, 5, 7, 11, 13, 17, 19, 23, 29

💡 If differences don't work in 20 seconds, try ratios, then alternating terms.

Alphabet Positions

EJOTYE=5, J=10, O=15, T=20, Y=25
Opposite pairPosition + opposite = 27 (A↔Z, M↔N)
Reverse position27 - forward position

💡 Write A-Z with numbers once on the rough sheet at the start of the exam.

Blood Relations

Draw: + male, - female, = couple, vertical line for generations
'Only son of my grandfather' = my father (paternal side)
Mother's or father's brother = uncle; their child = cousin

💡 Never decide gender unless the question gives it.

Direction and Distance

Right turnsN → E → S → W (clockwise)
Left turnsN → W → S → E
Shortest distance√(x² + y²)
ShadowMorning sun in the east, shadow falls west

💡 Mark the start point as (0, 0) and track x and y separately.

Syllogism Rules

All A are B: some B are A follows; all B are A does not
Some A are B: some B are A follows
No A is B: no B is A follows
Two 'some' statements give no definite conclusion

💡 Draw the minimum-overlap Venn diagram; a conclusion must be true in every possible diagram.

Clock and Calendar

Clock angleθ = |30H - 5.5M|
Hands overlapEvery 65 5/11 minutes
Odd daysNormal year 1, leap year 2
Leap centuryDivisible by 400 (2000 yes, 1900 no)

💡 For calendar questions count odd days, not days.

Mirror, Water Image and Paper Folding

Mirror (vertical)Left and right swap, top and bottom stay
Water imageTop and bottom swap, left and right stay
Paper foldingEach fold doubles the holes when unfolded

💡 Check one asymmetric detail (a dot, a corner) first; it rules out two options fast.

Mathematical Operations

Rewrite the expression with real signs first
Then apply BODMAS: ÷ and x left to right, then + and -

💡 Most wrong answers come from solving before substituting all the signs.

Exam Day Hacks & Reasoning

Negative-marking maths for both papers

Paper I (+1, -0.25): a blind guess among 4 options averages 0.25 x 1 - 0.75 x 0.25 = +0.06 marks, and a 50-50 guess averages +0.375. Paper II (+3, -1): a blind guess averages exactly 0, while a 50-50 guess averages +1. So in both papers, guess only after you have removed at least one option, and never guess blind in Paper II.

Time split for Paper I

200 questions in 120 minutes is 36 seconds each. A workable order: General Awareness first (about 15-20 minutes, you either know it or you don't), then Reasoning (about 30-35 minutes), then Technical (about 60 minutes), keeping 5-10 minutes buffer. If technical is your strength, start there; the notice sets no sectional timer, so the order is your choice.

Use the on-screen aids, but only when needed

The notice provides a scientific calculator on screen and the IS 456:2000 table and steam table under 'Useful Data', and bans physical calculators and tables. Clicking a calculator is slower than mental maths for simple sums, so use it for roots, powers and logs, and open the tables only for values you cannot recall.

Play Paper I for a safe qualify

In 2026 Paper I only qualifies you for Paper II; it does not add to your final merit. Bank the questions you are sure of, avoid risky guesses that could pull you under the cut-off, and save your energy and revision for Paper II, where every question is worth 3 marks.

Don't panic over a tough shift

Per the notice, marks from different shifts are normalised, and Mechanical and Electrical scores are normalised against each other. A paper that feels hard is usually hard for everyone in that shift, so keep your method instead of guessing more.
