In short
RRB's 4 November notice for the NTPC UG typing test says you must type at least 300 words in English or 250 in Hindi in 10 minutes, and explains how mistakes cut your speed. You still need 30 wpm in English or 25 in Hindi to qualify.
If you're on the NTPC UG typing test list, read this one properly. RRB put out a notice on 4 November 2026 (CEN 07/2025) that explains how the test will run and how your speed will be calculated. It follows the 2 November notice that gave the tentative dates. The PDF is linked below.
You need 30 words a minute in English or 25 in Hindi to qualify. You'll type in the language you choose on the RRB portal by 18 November. If you don't choose, it'll be English. Here's how to choose.
On the day
First you get one minute to practise and get a feel for the keyboard. Then there's a five-minute break, and then the real test for 10 minutes. Only those 10 minutes are marked.
You have to type at least 300 words in English or 250 in Hindi. If you type less than that, RRB won't check your passage at all. If you finish the passage early, you can start it again from the top, so keep typing till the time runs out.
You can't use editing tools to fix mistakes. The notice doesn't say which tools it means, so practise with autocorrect and spell-check switched off.
How your speed is worked out
RRB counts full mistakes and half mistakes. Two half mistakes make one full mistake. The notice doesn't say what counts as a full mistake and what counts as a half one.
Then it lets off mistakes equal to 5% of the words you typed. Type 400 words and your first 20 mistakes are forgiven. Whatever is left over is your final mistake count.
Each of those final mistakes takes 10 words off your total, and the rest is divided by 10 minutes. RRB's example in the notice: 400 words with 10 final mistakes. Take off 100 words, you're left with 300, and that's 30 words a minute.
What this means for your practice
I worked these out from the formula. They aren't in the notice.
Every final mistake costs you one word a minute. If you type 400 words in English, you can make 30 mistakes in total and still just pass, because 20 of them are let off.
At exactly 300 words you've got no spare speed. Only 15 mistakes are let off, and one more than that puts you below 30. In Hindi at 250 words, the limit is 12 and a half.
So when you practise, don't stop at 300. Try to reach 350 to 400 words in 10 minutes in English, or around 300 in Hindi. Then a few nervous slips on the day won't fail you.
