RRB NTPC CBTST rules
From the special instructions issued by Railway Recruitment Boards for the computer based typing skill test:
- A 1-minute practice, a 5-minute break, then the 10-minute test that is evaluated.
- Minimum 300 words in English or 250 words in Hindi in 10 minutes. Transcripts below this are not evaluated.
- If you finish the passage early, you may start it again from the beginning within the 10 minutes.
- Editing tools for correcting typed matter are not permitted.
- Errors are full or half mistakes. Total mistakes = full + half ÷ 2.
- Mistakes up to 5% of the total words typed are ignored.
- Speed = (total words typed − final mistakes × 10) ÷ time in minutes.
Worked example
You type 400 words in 10 minutes with 26 full and 8 half mistakes. Total mistakes = 26 + 4 = 30. Five percent of 400 is 20, so final mistakes = 30 − 20 = 10. Speed = (400 − 10 × 10) ÷ 10 = 30 WPM, just enough to qualify. Every final mistake costs 10 words, so a few extra mistakes can drop you below 30.
Our simulation turns backspace off, as in the exam, and reports full and half mistakes. Its pass check uses net WPM with a 5% error limit, which is close to the railway rule; use the worked formula above on your counts for the exact railway figure.
Preparing for the railway test
- Practise with backspace off. Learning to keep going after a mistake is the main skill this test checks.
- Aim to type 400+ words in 10 minutes in English (350+ in Hindi), so the 5% allowance covers normal slips.
- Hindi typists: practise on the Hindi typing test with your exam layout and a 25 WPM target.
