What mocks are for at each stage
Early on, topic tests turn syllabus coverage into speed: a test of 10 to 15 questions after each topic shows whether you can answer at 40 seconds a question. In the middle phase, sectional tests build the pace of each section. In the last two months, full-length CBTs rehearse the whole 90 minutes, the section order and your composure. A common mistake is to take full papers from the start and to conclude "I am slow", without finding which topics cost time. Another is to ignore the large, quick sections (General Awareness, General Science) because they feel unstructured, when they are the cheapest source of marks.
Stage 1: topic tests while you study
After each topic, take a short timed test. For arithmetic, aim for 40 to 60 seconds a question; for reasoning families, 30 to 40 seconds; for awareness and science, 15 to 20 seconds. Record error types. Use the topic pages such as percentage, HCF and LCM, mensuration, number series and direction sense.
Stage 2: sectional tests
When the topics are covered, take 25 to 40 question sectionals under a clock of about 54 seconds per question, two or three times a week, rotating the sections. Record attempts, accuracy and finishing time. Sectionals show exactly how long each section takes you: if you finish 40 General Awareness questions in 18 minutes at 85% accuracy, you can afford more time for Mathematics. Use the section pages: Mathematics, Reasoning and General Awareness.
Stage 3: full CBT papers
From about two months before the exam, take a full 100-question paper once a week, on a computer, in the time slot you expect. Treat it as the real exam. Review it the next day. In between, use sectional tests to repair what the paper exposed.
Choosing your section order
Because there is typically one 90-minute clock and you can move between sections, the order is yours to decide. A plan to test for NTPC CBT-1:
| Order | Time plan (90 minutes) |
|---|---|
| General Awareness first | GA (40): 20 minutes; Reasoning (30): 28 minutes; Mathematics (30): 32 minutes; review: 10 minutes |
| Reasoning first | Reasoning: 26 minutes; GA: 22 minutes; Mathematics: 32 minutes; review: 10 minutes |
| Mathematics first | Mathematics: 32 minutes; Reasoning: 26 minutes; GA: 22 minutes; review: 10 minutes |
Run each order for two papers and compare net scores, accuracy and how you felt. Candidates who are strong in GA often prefer to start there, because it banks marks and settles the nerves; others find that doing Mathematics first, while fresh, protects accuracy. The right choice is the one your data supports. For Group D, adapt the plan to the four sections, taking General Science and General Awareness quickly.
A sample week in the full-test phase
| Day | Task |
|---|---|
| Monday | Review of the weekend paper: classify errors; error log |
| Tuesday | Mathematics sectional (30 questions in 32 minutes) and topic repair |
| Wednesday | Reasoning sectional (30 questions in 28 minutes); one weak family drill |
| Thursday | General Awareness and General Science quizzes (40 questions); update the miss list |
| Friday | Light day: formulas and facts |
| Saturday | Optional sectional or rest |
| Sunday | Full 100-question CBT in the exam time slot |
Reviewing a railway mock: a method
- Within an hour, note how each section felt and where you lost time.
- Record per section: attempts, correct, wrong, net score, time used.
- Classify every wrong answer: concept or fact gap, calculation error, speed problem, reading error, guess error or outdated fact.
- Look at the questions you did not attempt: could you have answered them in the time?
- Redo the slowest questions with a faster method.
- Write one change for the next paper.
An example of using the numbers
Suppose a candidate records the following over three papers (illustrative figures, out of 40, 30 and 30):
| Paper | General Awareness | Reasoning | Mathematics | Total |
|---|---|---|---|---|
| 1 | 27.0 | 20.5 | 16.0 | 63.5 |
| 2 | 30.5 | 23.0 | 20.5 | 74.0 |
| 3 | 33.0 | 24.5 | 24.0 | 81.5 |
General Awareness rose by six marks (revision and quizzes), Mathematics by eight (speed drills and shortcuts) and Reasoning by four. The numbers show where to push next: Mathematics is still the weakest in relative terms (24 of 30 against 33 of 40), and Reasoning has the smallest gain. Without the table the candidate would see only that the total rose.
Dealing with negative marking
With a one-third penalty the break-even accuracy is 25%. Use your own data: in your mocks, tag guessed answers and compute net marks. If guesses after eliminating one option are right more than a third of the time, they pay; if not, leave them. Do not guess blindly in the last minutes: the expected value is zero, and the risk is variance. See our negative marking guide.
Common mistakes with mocks in railway preparation
- Taking only full papers.
- Ignoring the science section for Group D.
- Always starting with the same section without testing alternatives.
- Not keeping a miss list for awareness facts.
- Reviewing only wrong answers, not slow correct ones.
The last month and the last week
In the last month, two full papers a week at most, with revision of formula sheets, vocabulary of science terms and fact lists. In the last week, take a final paper four or five days before the exam, review it lightly and rest. The exam-day checklist covers the logistics.
