Mastering Time in RRB NTPC CBT 2: Subject‑wise Speed Tricks

If you are gearing up for RRB NTPC CBT 2, the biggest enemy is not the syllabus – it is the clock. The paper gives you 120 minutes for 100 questions, which translates to 1.2 minutes per question. Most candidates finish with 10‑15 minutes left, while a few run out of time before the last section. The difference lies in how you handle each subject.

Understanding the CBT 2 Pattern

The test is divided into four sections: General Awareness, Mathematics, Reasoning, and General English. Each section carries 25 marks, and every wrong answer attracts a -0.25 penalty. The order of sections is fixed, so you cannot jump between them.

Because each section gets an equal slice of the clock, you must finish a section in roughly 30 minutes. That means 1.2 minutes per question, but the real target is 45 seconds for easy items and 90 seconds for tough ones.

Subject‑wise Time Allocation

Start each section with a quick scan. Mark questions that look straightforward and set them aside for a first pass. Reserve the last 5 minutes of the 30‑minute block for review and doubtful items.

The first pass tackles questions you can solve in under a minute. The second pass deals with medium‑difficulty items that need a quick calculation or two‑step logic. The review slot is for checking flagged questions and eliminating negative marking.

Speed Tricks for General Awareness

• Year‑wise shortcut: Keep a list of important years (e.g., 1947, 1991, 2000) and their events. When a year appears, you instantly know the context.
• Current affairs flashcards: Use a set of 200 cards covering the last 12 months. Flip through them twice a week; recognition time drops to 2‑3 seconds per fact.
• Elimination rule: If three options belong to the same category (e.g., all Indian states) and one does not, the odd one out is usually correct.

Apply the first pass rule: answer any question that matches a memorised year or a flashcard instantly. If you need to think, move on and flag it.

Speed Tricks for Mathematics

• Multiplication shortcuts: For numbers ending in 5, multiply the preceding digit by the next integer and append 25 (e.g., 75 × 75 = 5 × 8 = 40 → 5625).
• Square of numbers ending in 5: Same rule works for any two‑digit number ending in 5.
• Percentage of 5, 10, 20, 25, 50: Halve, quarter, double, etc., instead of long division.
• Quick LCM/GCD: Use prime factorisation for numbers ≤ 100; write down the highest powers for LCM, lowest for GCD.

During the first pass, solve any problem that fits one of these patterns. For example, a question asking 15 % of 240 can be done as 10 % (24) + 5 % (12) = 36 in a heartbeat.

Speed Tricks for Reasoning

• Direction‑based puzzles: Convert “left” and “right” into +1 / –1 moves on a number line. This reduces mental rotation.
• Series completion: Look for common differences or ratios first; if none, check alternating patterns.
• Seating arrangement: Sketch a quick 3 × 3 grid, place the fixed person, then fill relative positions. Use symbols (↔, ↑, ↓) to avoid writing full names.
• Data‑sufficiency: If the first statement alone gives a unique answer, mark it and skip the second.

Mark any puzzle that fits a known template and solve it in the first pass. If you need to draw a diagram, allocate no more than 30 seconds before moving on.

Speed Tricks for General English

• Reading comprehension: Scan the passage for keywords (however, therefore, because). Answer the question by locating the sentence containing the keyword; you rarely need to read the whole paragraph.
• Error spotting: Look for subject‑verb disagreement first, then verb tense, then preposition misuse. Most errors fall into these three buckets.
• Vocabulary in context: Eliminate options that are synonyms of the opposite meaning; the correct word usually fits the tone of the sentence.
• Fill‑in‑the‑blank: Use the “collocation test” – does the word commonly pair with the surrounding words? If not, discard it.

During the first pass, answer any question where the keyword instantly points to a line. If you need to read the whole passage, flag it for the second pass.

Mock Test Strategy

Take a full‑length mock every weekend. Follow the exact 30‑minute per section timing. After the test, spend 30 minutes analysing every mistake. Note down the pattern that caused the slip – e.g., “missed a negative‑mark question because I didn’t flag it”.

• Record your average time per question for each section.
• Identify the top three slowest question types.
• Create a personal cheat‑sheet for those types and rehearse it for a week.

Repeat the cycle until your first‑pass accuracy climbs above 70 % and your average time drops below 45 seconds for easy items.

Final Checklist Before the Exam Day

• Print the time‑allocation table and keep it on your desk.
• Carry a small notebook with the multiplication, percentage and reasoning shortcuts.
• Set your watch to give a silent 30‑minute alarm for each section.
• Sleep at least 7 hours the night before; fatigue kills speed.

Follow these habits, and you will finish each section with minutes to spare for a quick review. The extra buffer often turns a borderline score into a clear cut‑off.
