How to Prepare for RRB Group D (Level-1) 2026

Start physical training in PARALLEL with study from Day 1. A surprisingly high number of strong CBT scorers fail PET — especially the 35 kg / 100m / 2 min lift-and-carry, which catches lean candidates off guard. Build grip strength, shoulder endurance and basic cardio (1 km run) at least 12-16 weeks before the PET date.

For Mathematics, NCERT Class 8-10 textbooks cover everything in the CBT. R.S. Aggarwal Quantitative Aptitude (10th-pass chapters only — percentage, ratio, average, profit-loss, SI/CI, time-work, time-speed-distance, basic mensuration) is more than enough. Skip advanced shortcuts — Group D doesn't reward them.

Reasoning rewards practice volume over technique. 20-30 questions a day from series, coding, analogies, blood relations and direction sense for 60-90 days makes a real difference. R.S. Aggarwal Verbal & Non-Verbal Reasoning is the standard book.

General Science — read NCERT Class 9 and 10 Science (Physics + Chemistry + Biology chapters) cover to cover. Don't skip diagrams or in-text examples. Lucent's General Science is a good quick-revision supplement.

GK and Current Affairs — Lucent's General Knowledge (Hindi or English) is the bible for static GK. For current affairs, read one daily summary (Adda247 free PDFs, Career Power monthly bulletin, or Pratiyogita Darpan / Manorama Yearbook for deeper context). Indian Railways general facts (zones, major routes, well-known records) are high-yield — don't skip them.

Hindi-medium aspirants have a slight advantage in this exam — official notification, question paper and most prep books are widely available in Hindi. Use whichever language you are most comfortable in; don't switch mid-prep just because friends do.

Take 3-5 full-length mock tests in the last 4 weeks to handle the 90-minute pressure across 100 questions. Aim for 70-75+ attempts with 90%+ accuracy — negative marking is -1/3, so blind guessing on 5+ questions hurts.
