SSC Examination cheat sheet

Stress = Force/Area; strain = change in length/original length; Young's modulus E = stress/strain in the elastic region.

Bending moment at a simply supported beam under central point load W and span L is WL/4; maximum deflection is WL³/48EI.

For a rectangular section, section modulus Z = bd²/6 and moment of inertia I = bd³/12, so bending stress = M/Z.

In a three-phase system, power P = √3 × V_L × I_L × cos φ; for a single-phase circuit P = V I cos φ.

Transformer EMF equation: E = 4.44 f N Φ_max, where f is frequency, N turns and Φ_max peak flux.

Concrete nominal mixes: M15 = 1:2:4, M20 = 1:1.5:3, M25 = 1:1:2 (cement:sand:coarse aggregate) by volume.

Slump test measures workability of concrete; the standard slump cone has a top diameter of 100 mm, bottom 200 mm and height 300 mm.

In a four-stroke engine, one thermodynamic cycle takes two revolutions of the crankshaft; in a two-stroke engine, one revolution.

Tier I is computer-based with four sections: General Intelligence, General Awareness, Quantitative Aptitude and English Language, 25 questions each.

Tier I negative marking is 0.50 mark per wrong answer; questions unattempted carry no penalty.

Tier II consists of separate computer-based modules (mathematical abilities, reasoning, English, general awareness, computer knowledge and skill test/typing as applicable).

For the typing test, the usual requirement is about 35 words per minute in English or 30 words per minute in Hindi, with accuracy assessed.

Percentage change = (new value − old value)/old value × 100; a successive rise of a% then b% gives net change a + b + ab/100.

Simple interest = P × R × T/100; compound interest = P[(1 + R/100)^T − 1].

Average = sum of observations/number of observations; if each value rises by k, the average rises by k.

Ratio problems: if a:b = 3:4 and b:c = 5:6, then a:b:c = 15:20:24 by equalising the common term.

The Computer Based Examination has 80 objective questions: General Intelligence and Reasoning 20, General Knowledge and General Awareness 20, Elementary Mathematics 20, English/Hindi 20.

Total marks are 80, with 1 mark per question and a negative marking of 0.25 mark for each wrong answer.

The examination duration is 60 minutes; the paper is bilingual (English and Hindi).

Physical Standard Test norms differ by region and gender; height, chest and weight are measured against the notified regional standards.

Physical Efficiency Test for male candidates typically requires 5 km run within 24 minutes; for female candidates 1.6 km within 8 minutes 30 seconds (as notified).

Elementary mathematics covers number system, percentages, averages, ratio and proportion, profit and loss, time and work, and simple interest.

Static GK emphasis: Indian polity, geography, history, science, current affairs, sports and national symbols.

Reasoning topics include analogies, series, coding-decoding, syllogism, direction sense, blood relations and non-verbal figures.

The examination tests translation from English to Hindi and Hindi to English along with an essay and general knowledge components, as per the notified scheme.

Translation should preserve meaning and register; literal word-for-word rendering is rejected in favour of idiomatic equivalence.

Administrative terminology must follow the official bilingual glossary, e.g. 'Cabinet Secretariat', 'Comptroller and Auditor General'.

Essay writing is assessed on structure, relevance, coherence and language correctness, not length alone.

Idioms and proverbs rarely translate literally; an equivalent Hindi muhavara is required to convey the intended sense.

Technical and legal terms with no Hindi equivalent are commonly retained in transliterated form, optionally with the English term in brackets.

Accuracy of grammar, spelling and punctuation in both languages carries weight; inconsistency in terminology is penalised.

Passages often drawn from official documents, speeches and reports require formal, impersonal style.

Paper I is computer-based with General Intelligence and Reasoning, General Knowledge and General Awareness, Quantitative Aptitude, and English Comprehension.

Paper II comprises English language and comprehension testing grammar, vocabulary, sentence structure and writing ability.

Negative marking is 0.25 mark for each wrong answer in objective papers; unattempted questions carry no penalty.

Male candidates for Delhi Police and CAPF posts must qualify the Physical Endurance Test, typically a long-distance run plus events such as long jump and high jump (norms as notified).

Physical Standard Test specifies minimum height and chest measurements, with relaxations for hill-area and certain category candidates.

General Awareness includes Indian polity, constitution, history, geography, economy, science and current events.

Quantitative Aptitude covers number system, HCF/LCM, percentages, ratio, averages, time-work, speed-distance, mensuration and data interpretation.

Driving test is required for certain posts such as Sub-Inspector (Driver) in Delhi Police.

Selection Posts are categorised by educational qualification level: Matriculation, Higher Secondary (10+2) and Graduation and above.

The computer-based examination has three parts: General Intelligence, General Awareness and Quantitative Aptitude, with part-wise question counts varying by level.

Negative marking is 0.50 mark per wrong answer for the Graduation-level posts and 0.25 mark for Matriculation and Higher Secondary levels, as notified.

Skill tests (typing, data entry, computer proficiency) apply only to posts where the notified post specification requires them.

The examination is qualifying in nature for shortlisting; final merit considers the CBT score, subject to post-specific requirements.

General Intelligence covers analogies, series, coding-decoding, syllogism, classification and spatial reasoning.

Quantitative Aptitude at Matric level emphasises arithmetic; Graduation level adds algebra, geometry and data interpretation.

Eligibility is determined strictly by the post's notified educational qualification and age band, not by the highest degree held.

Tier I is computer-based with four sections of 25 questions each: General Intelligence and Reasoning, General Awareness, Quantitative Aptitude, and English Comprehension, 100 marks total.

Tier I negative marking is 0.50 mark per wrong answer; Tier II module-wise marking is 1 mark per question with a 0.25 penalty for wrong answers.

Tier II comprises separate modules including mathematical abilities, reasoning, English, general awareness, computer knowledge and, for some posts, statistics or finance and economics.

Sectional qualifying cut-offs apply in Tier II; overall merit is computed from Tier I plus Tier II scores as notified.

For posts requiring typing, English typing at 35 wpm or Hindi typing at 30 wpm is tested, with errors deducted.

Quantitative topics: percentages, ratio, averages, interest, profit and loss, time-work, speed-distance, algebra, geometry, trigonometry and data interpretation.

English Comprehension tests reading comprehension, grammar, vocabulary (synonyms, antonyms, idioms) and sentence correction.

General Awareness covers history, polity, geography, economy, science and current affairs with a static-knowledge bias.

The computer-based examination has three parts: General Intelligence and Reasoning (50 questions, 50 marks), General Awareness (50 questions, 50 marks) and English Language and Comprehension (100 questions, 100 marks).

Negative marking is 0.25 mark for each wrong answer in the objective test.

The skill test in stenography requires dictation at 10 minutes at 100 words per minute, followed by transcription: 40 minutes in English or 55 minutes in Hindi on computer.

The transcribed matter must be typed on a computer; the number of mistakes allowed is limited (about 5 per cent of the dictated matter) as notified.

Grade 'C' posts generally require higher pay-level eligibility and are filled through higher merit; Grade 'D' is the entry grade.

English Language section covers grammar, vocabulary, sentence improvement, error spotting, fill in the blanks and comprehension.

General Awareness includes Indian polity, history, geography, economy, science and current affairs.

Speed building for stenography depends on consistent practice of outlines and transcription accuracy, not only dictation speed.
