In this guide
You do not need to leave your job or your course to prepare for RRB Group D. The syllabus is Class 10 level, and the paper has 100 questions. What it needs is steady hours over months, not a heroic month at the end. Two to three focused hours on a working day, and more at weekends, is enough if you use them well.
The hard part is not the study. It is fitting study, work, family and PET training into one day without burning out. This guide is about that.
First, count your hours
Suppose an aspirant can manage this every week:
| Day | Study | Physical training |
|---|---|---|
| Monday to Friday | 2.5 hours a day | 30–45 minutes |
| Saturday | 4.5 hours | 45 minutes |
| Sunday | 5.5 hours, including a mock | Light, or rest |
That is 5 × 2.5 = 12.5 hours on weekdays, plus 4.5 + 5.5 = 10 hours at the weekend: 22.5 hours a week. Over 16 weeks it adds up to 360 hours. That is plenty for this syllabus, as long as the hours are real study and not time spent with a book open and a phone beside it.
Splitting the hours
| Section | Questions | Share of study time | Hours out of 360 |
|---|---|---|---|
| Reasoning | 30 | About 25% | 90 |
| Mathematics | 25 | About 30% | 108 |
| General Science | 25 | About 25% | 90 |
| General Awareness | 20 | About 10% | 36 |
| Mocks and analysis | All | About 10% | 36 |
Maths gets a little more because speed takes practice. GA gets less in dedicated hours because most of it happens in small daily pockets. Shift the split towards your weakest section after your first mock.
A weekday timetable
| Time | Activity |
|---|---|
| Early morning | Running and strength exercises (30–45 min) |
| Before work or college | Maths or reasoning (1 hour) |
| Travel and breaks | GK notes, science flashcards, 5–10 reasoning questions |
| Evening | Science or reasoning (1–1.5 hours) |
| Before sleep | 15 minutes of revision of the day's notes |
Put the subject that needs the sharpest mind, usually maths, in the slot when you are freshest. For most people that is before work, not after.
If you work shifts or nights
Rotating shifts break a fixed timetable. Instead of fixed clock times, fix the order:
- After waking and eating: one hour of maths or reasoning.
- Before leaving for work: 30 minutes of science.
- During breaks: GA and flashcards.
- On the day off: a mock and its analysis.
On night-shift weeks, move the running to the evening before your shift, and don't cut sleep to study. A tired mind makes the careless mistakes that negative marking punishes.
If you are still in ITI or college
- Your course has exams and practicals too. Don't drop them. An incomplete qualification makes you ineligible.
- Use college free periods for GA and science reading.
- ITI students already know some basic science and workshop terms. That is an advantage in General Science.
Use small pockets of time
- Ten minutes is enough for five reasoning questions or twenty GK facts.
- Keep a small notebook of facts in your pocket, or photos of your notes on your phone.
- Replace some phone scrolling with a quick quiz.
- Say squares and tables aloud while walking: 17² is 289, 18² is 324, 19² is 361.
Six pockets of ten minutes a day is an extra hour, and it adds up to about 7 hours a week.
Fitting in the PET
The PET needs months of training, so it cannot wait until the CBT result.
- Run in the early morning, before work. Start with a walk–jog and build up.
- Do bodyweight exercises (squats, push-ups, plank) three times a week.
- Practise carrying a loaded bag or sack at weekends, building up the weight slowly.
- If your job is physical, count it as part of your strength work and keep the running light on heavy days.
The targets are a 1,000 m run in 4 minutes 15 seconds for men and 5 minutes 40 seconds for women, and a weight carry of 35 kg (men) or 20 kg (women) for 100 m in 2 minutes. See the PET standards guide for a training plan.
A sample weekend
| Time | Saturday | Sunday |
|---|---|---|
| Early morning | Run (intervals) | Easy run or rest |
| Morning | Maths and reasoning (3 hours) | Full mock test (90 minutes) |
| Afternoon | Rest | Mock analysis (1 hour) |
| Evening | Science and GK (1.5 hours) | Weekly revision; weight-carry practice |
Handling tiredness
- Study the hardest subject when you are freshest.
- Sleep at least seven hours. Tired study is mostly wasted study.
- Take one evening off every week and actually rest.
- If a day goes wrong, do 30 minutes of revision rather than nothing. The habit matters more than the day.
Plan your leave early
The CBT, the PET and document verification each need a day or more away from work or college, and the centre may be in another city.
- As soon as your exam city and date are announced, tell your employer or college and apply for leave.
- Plan travel, including a night's stay if the centre is far away.
- If you work in a government office, check whether you need permission to apply and a No Objection Certificate for document verification.
Staying motivated
- Keep a weekly record of study hours, mock scores and running times. Progress you can see keeps you going.
- Tell your family your plan and ask for a quiet hour at fixed times.
- Write down why you want this job and keep it where you can see it.
Your first week
- Take one full mock to see where you stand.
- Write down your real weekly hours, not the ideal ones.
- Fix your morning slot for running and your freshest slot for maths.
- Prepare a pocket notebook for GK and science facts.
- Read our three-month plan and fit it to your hours.
