Free RRB NTPC Exam Flashcards

The common path is CBT 1, CBT 2, then a post-specific CBAT or Typing Skill Test where required, followed by document verification and medical examination.

CBT 1 has 100 questions: 40 General Awareness, 30 Mathematics, and 30 General Intelligence & Reasoning. Each question carries 1 mark.

CBT 2 has 120 questions: 50 General Awareness, 35 Mathematics, and 35 General Intelligence & Reasoning. It is usually more decisive for merit than CBT 1.

For each wrong answer in CBT 1 or CBT 2, one-third of the mark for that question is deducted. Leaving a question blank avoids the penalty.

Local metadata lists minimums as 40% for UR/EWS, 30% for OBC-NCL and SC, and 25% for ST. Final cut-offs vary by category, zone, post, and vacancies.

RRB uses normalisation when exams run in multiple shifts. It adjusts scores for shift-level difficulty differences before preparing merit lists.

The Computer Based Aptitude Test is post-specific, notably for Station Master and Traffic Assistant. It is qualifying in each test battery and contributes to final merit for those posts.

Typing applies only to designated clerical or typist posts. The local metadata records qualifying speeds of 30 wpm in English or 25 wpm in Hindi.

General Awareness is the largest section in both CBT stages. It rewards steady revision across current affairs, railways, polity, history, geography, economy, science, and static GK.

Lord Dalhousie is commonly linked with the introduction of railways in India. Remember him with the first passenger railway era in the 1850s.

India's first passenger train ran on 16 April 1853 between Bori Bunder in Mumbai and Thane. This is a core railway-history fact.

Indian Railways operates under the Ministry of Railways through the Railway Board, which is the apex body for railway policy, administration, and operations.

Vande Bharat Express, also known as Train 18, is India's first indigenously designed semi-high-speed train service.

Article 32 protects the Right to Constitutional Remedies, allowing citizens to approach the Supreme Court to enforce Fundamental Rights.

Article 79 describes Parliament as consisting of the President, the Lok Sabha, and the Rajya Sabha.

The 44th Amendment removed the Right to Property from Fundamental Rights and placed it as a constitutional/legal right under Article 300A.

The Quit India Movement began in 1942 with Gandhi's call to end British rule. It is associated with the slogan 'Do or Die'.

In 1526, Babur defeated Ibrahim Lodi at the First Battle of Panipat, marking the beginning of Mughal rule in India.

Nitrogen is the most abundant atmospheric gas, making up about 78% by volume. Oxygen is second at about 21%.

Photosynthesis is how green plants use sunlight, carbon dioxide, and water to make glucose and release oxygen. Chlorophyll captures the light energy.

Insulin is produced by beta cells in the pancreas. It helps regulate blood glucose by moving sugar from the blood into body cells.

The Ganga is generally treated as the longest river flowing within India. It is important for geography, agriculture, transport, and culture.

The Tropic of Cancer passes through eight Indian states, making it a frequent static-GK geography fact.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and later became India's central bank after nationalisation.

Goods and Services Tax came into effect in India on 1 July 2017, replacing many indirect taxes with a unified framework.

Work through Brackets, Orders, Division/Multiplication, then Addition/Subtraction. In exam arithmetic, handle 'of' or multiplication before addition and subtraction.

HCF is the greatest factor common to the numbers; LCM is the smallest number divisible by all of them. Prime factorisation makes both faster.

A percentage means 'per 100'. Convert by dividing by 100: 75% = 75/100 = 3/4, and 3/4 = 75%.

For an increase of a% followed by a decrease of a%, the net change is a loss of a^2/100 percent. Example: +20% then -20% gives -4%.

For an odd count of consecutive even or odd numbers, the average is the middle number. Build the sequence around that middle value.

Profit% = (Profit / Cost Price) x 100. Always compare profit or loss to cost price, not selling price.

Simple Interest = (Principal x Rate x Time) / 100. If a sum doubles under simple interest, the interest equals the principal.

Compound interest earns interest on the growing amount. For annual compounding, Amount = P(1 + R/100)^T, then CI = Amount - P.

Multiply by 5/18 to convert km/h to m/s. Example: 54 km/h becomes 15 m/s.

When two objects move toward each other, add their speeds. Time to meet = distance between them / combined speed.

If A takes x days and B takes y days, their one-day work is 1/x and 1/y. Together, add the rates and invert the result.

If a total is divided in the ratio a:b, first find one part as total / (a + b), then multiply by a or b for each share.

Area = pi r^2. For radius 7 and pi = 22/7, the area is (22/7) x 7 x 7 = 154 square units.

For x^2 - 5x + 6, find two numbers with sum 5 and product 6: 2 and 3. So the factors are (x - 2)(x - 3).

Cancel common factorial terms before multiplying. For example, 7! / 5! = 7 x 6 because 5! cancels out.

Identify whether each letter moves by a fixed number of places. CAT to DBU is a +1 shift; MANGO to OCPIQ is a +2 shift.

Translate every relationship into a simple family link before answering. Phrases like 'only son' or 'only daughter' usually identify one specific person.

Find the common property of most options, then choose the one that breaks it. The property may be category, number type, shape, use, or sequence rule.

Name the relationship first: tool-function, person-place, part-whole, cause-effect, or degree. Then pick the option with the same relationship.

Check differences, multiplication, alternating terms, squares/cubes, and alphabet movement. Do not settle on a pattern until it explains every given term.

If all A are B and all B are C, then all A are C. For 'some' statements, only conclude what must follow from the overlap.

Draw a quick north-east-south-west path and mark each turn. The final displacement from the start gives the answer, not the total distance walked.

For days after a given weekday, divide the number of days by 7 and use the remainder. A remainder of 2 means move two weekdays ahead.

Each hour mark equals 30 degrees. At 3:00, the hands are three marks apart, so the smaller angle is 90 degrees.

Position from the other end = total people - given position + 1. For 40 people and 12th from the left, the right-side position is 29th.
