RRB NTPC Typing Skill Test — Quick Facts
The RRB NTPC Typing Skill Test (TST) is a qualifying round conducted by Railway Recruitment Boards for Junior Clerk cum Typist, Accounts Clerk cum Typist, and Junior Time Keeper posts at UG level, and Senior Clerk cum Typist, Junior Account Assistant cum Typist, and Senior Time Keeper posts at Graduate level. It carries no merit marks. You pass or fail based entirely on net speed and accuracy. Candidates who clear CBT 1 and CBT 2 with strong scores get eliminated here because they treated a 10-minute typing test as an afterthought.
English candidates need 30 WPM net. Hindi candidates need 25 WPM net. Net speed is not gross speed. RRB uses a four-step formula: total mistake points (Full mistakes + Half mistakes ÷ 2), minus a 5% buffer on total words typed, equals final mistake count. Each final mistake deducts 10 words. Divide remaining words by 10 minutes to get net WPM. At 300 words typed, the 5% buffer covers 15 mistake points before any penalty starts — but each mistake point beyond that costs 10 words from your total.
The condition that eliminates the most prepared candidates is this: Backspace, Delete, and all arrow keys are disabled for the full 10 minutes. Once you type a character, it stays. The system scores your transcript after the session ends — no error feedback appears on screen during the test. Candidates who trained on platforms that allow correction reach for Backspace on exam day and get nothing. That reflex, if not trained out, costs rhythm and leaves errors uncorrected. Every RRB NTPC practice session should run with correction keys disabled from Day 1.
This page covers the four-step net WPM formula with a worked example, Full and Half mistake definitions, the no-correction interface rules, Hindi font and layout options (Kruti Dev 010 with Remington Gail, or Mangal Unicode with Inscript), PwBD provisions, and a preparation approach built around the no-backspace condition. Graduate and UG levels use the same formula and the same speed cutoffs — only the eligible posts and pay levels differ.
Backspace disabled
Once a character is entered it cannot be removed. No Delete, no arrow keys. Train without correction from Day 1 — the exam interface enforces it.
5% buffer built in
At 300 words typed, the first 15 mistake points are forgiven before any penalty applies. Beyond that, each final mistake deducts 10 words from your total.
Qualifying only
Zero marks added to merit. Failing eliminates you regardless of your CBT 1 and CBT 2 scores. Graduate and UG levels use the identical formula.

Speed Required
30 WPM net for English, 25 WPM net for Hindi. Net WPM is what gets scored — not gross. The four-step formula applies error deductions after a 5% buffer, so the number that shows on your practice session is not the number RRB calculates. Type 300 words in 10 minutes and finish with more than 15 mistake points, and the 10x penalty starts cutting your total fast. The English passage runs approximately 1,500 characters; Hindi runs approximately 1,250 characters — enough text to maintain target speed for the full session.

Nature | Qualifying only — zero merit marks |
RRB NTPC states the requirement in WPM only — KDPH is not the official unit here. 30 WPM × 5 key depressions × 60 minutes = 9,000 KDPH equivalent if you need a reference. Practise at 35 WPM gross to build a buffer that covers error deductions and the no-backspace difficulty together.
Interface — What Is Allowed and What Is Not
Backspace, Delete, and all arrow keys are disabled for the full 10 minutes. A character entered cannot be removed. RRB scores your transcript after the session ends — no error count appears on screen while you type. You finish, the session closes, and then you see the result. Practise in the same condition: no corrections, no feedback, 10 minutes straight.
| Function | Status | What it means |
|---|---|---|
Backspace key | Disabled | Completely blocked for the full 10-minute evaluation. Once a character is entered it cannot be removed. Official notification: 'Use of editing tools for correcting the mistakes of the typed matter is not permitted.' |
Delete key | Disabled | Blocked alongside Backspace. No forward or backward deletion is possible during the test. |
Arrow keys (← → ↑ ↓) | Disabled | All four arrow keys are disabled. You cannot reposition your cursor to correct a previously typed character. |
Live error highlighting | None | No on-screen error feedback during the test. The system evaluates your transcript only after the session ends — you will not know your mistake count until the result screen. |
Tab key (new paragraph) | Required | Each new paragraph must begin with Tab. Starting with spaces instead counts as a half mistake — and since backspace is disabled, the error cannot be corrected once made. |
Copy / Paste | Disabled | Clipboard operations are completely blocked. No workaround exists. |
Spell-check / AutoCorrect | None | No assistance of any kind. Every character and space is your sole responsibility for the full 10 minutes. |
Passage scroll | No | Passage does not auto-scroll. Keep your reading 2–3 words ahead of your typing position to maintain rhythm without losing your place. |
How Errors Are Counted — Full and Half Mistakes
RRB NTPC uses Full and Half mistakes. Full mistakes cost 1 point each — wrong word, omitted word, added word, spelling error, repetition, incomplete word. Half mistakes cost 0.5 points each — spacing, capitalisation, punctuation, transposition, syllabification, faulty Shift key. Add them up, subtract the 5% buffer, and multiply what remains by 10 to get your word deduction. At 300 words with 25 total mistake points: buffer = 15, final count = 10, penalty = 100 words, net = (300 − 100) ÷ 10 = 20 WPM. A fail from a score that felt close.
FULL MISTAKES — 1 word each
Typing a wrong word in place of the given word
Omitting a word from the passage
Adding a word not present in the passage
Spelling error — any letter wrong, added, or omitted within a word
Wrong word repetition (entire repeated group counts as 1 mistake)
Leaving a word incomplete (half-typed, session ends before completion)
HALF MISTAKES — 0.5 word each
Missing space or extra space between words
Wrong capitalisation — uppercase where lowercase needed or vice versa
Punctuation mark omitted, added, or substituted
Word transposition — two adjacent words typed in the wrong order
Syllabification error — word incorrectly split across lines
Faulty Shift-key use — wrong character case from Shift key press
The Net-Speed Formula
net-wpm-formula
Total Mistakes = Full mistakes + (Half mistakes ÷ 2)
Buffer = 5% × Total words typed (mistakes forgiven)
Final Count = Total Mistakes − Buffer (minimum 0)
Net WPM = (Total words − Final Count × 10) ÷ 10 minutes
Graduate and UG level exams use the identical formula — only the eligible posts differ. No category-wise error relaxation applies; the 5% buffer is the same for all candidates. PwBD provisions (extended time or exemption) depend on the specific recruitment notification.

Net WPM
23.0 ✗ FAIL
400 words typed, 10 final mistakes after the buffer: 10 × 10 = 100 words deducted. Net WPM = (400 − 100) ÷ 10 = 30 WPM — exactly the pass mark. One additional final mistake drops you to 29 WPM. The 10x penalty makes each mistake beyond the buffer expensive.
Category-Wise Error Limits
RRB NTPC applies no category-wise error relaxation. The 5% buffer is the same for Unreserved, OBC, SC, ST, and EWS candidates. PwBD candidates with 40% or more permanent disability — Blindness/Low Vision, Cerebral Palsy, Loco Motor Disability — may receive extended time or exemption from the typing test. Check the official notification for your specific recruitment cycle to confirm PwBD provisions.
| Category | Max Errors Allowed | Min Accuracy |
|---|---|---|
Unreserved (UR) / EWS | ≤ 5% | ≥ 95% |
OBC / SC / ST / PwBD / ESM | ≤ 8% | ≥ 92% |
SSC CHSL gives OBC/SC/ST a 10% error ceiling against 7% for Unreserved. RRB NTPC gives everyone the same 5% buffer. A reserved category candidate and an Unreserved candidate face identical conditions — same buffer, same cutoff, same penalty formula.
Hindi Font Options
RRB NTPC Hindi typing accepts two combinations: Kruti Dev 010 with Remington Gail keyboard layout, or Mangal Unicode with Inscript keyboard layout. Your choice is fixed at application time and confirmed on your admit card. Both options are available at the exam centre — you select your layout when the session begins. UP Police mandates Mangal Inscript only; RRB NTPC lets you use whichever layout you trained on.
| Font / Layout | Keyboard Logic | Best Suited For |
|---|---|---|
Kruti Dev 010 | Remington Gail keyboard | Candidates trained on traditional typewriter-style Hindi layouts |
Mangal Unicode | Inscript keyboard | Candidates who learned Hindi typing on modern computer keyboards |
Pick one layout and stay on it. Switching between Remington Gail and Inscript even once resets matra muscle memory — vowel sign positions (ि, ी, ु, ू) differ significantly between the two. Verify your registered layout from your admit card before your first practice session.
Before You Start Practising
Disable backspace before your first session and keep it disabled for every RRB NTPC session. The correction reflex takes weeks to unlearn — do not build it in the first place.
Target 35 WPM gross for English and 29 WPM gross for Hindi. The 5 WPM margin above the cutoff covers error deductions under the 10x penalty formula and the speed drop from exam-day pressure and unfamiliar hardware.
After every session, calculate your final mistake count: (Full mistakes) + (Half mistakes ÷ 2) − (5% × words typed). If the result stays above 5 regularly, work on accuracy before raising your speed target.
Run full 10-minute sessions only. The mental fatigue from typing without correction for 10 minutes is not present in 3-minute bursts. You need to build composure for the final stretch, and short sessions do not do that.
Check your admit card for your Hindi layout before your first Hindi practice session. Set that layout in practice and stay on it. Remington Gail and Inscript have different key positions for vowel signs — switching mid-preparation forces relearning from scratch.
Read 2–3 words ahead of your current typing position. A lost reading position with no backspace forces a choice between stopping to find your place or guessing the next word. Both cost you. The reading-ahead habit removes both options from the equation.
Common Reasons People Fail
Practising with backspace enabled
Candidates who train with correction keys available build a reflex: spot error, reach for Backspace. On exam day, that reach does nothing. The error stays, the rhythm breaks, and the attempt cost was wasted time. Disable backspace in practice from your first session and keep it off.
Treating the 5% buffer as an error ceiling
The 5% buffer is not a percentage limit — it is a forgiveness threshold before the 10x penalty starts. At 300 words, the buffer covers 15 mistake points. Beyond that, each final mistake costs 10 words. Ten final mistakes at 300 words typed: 100 words deducted, net = 20 WPM. That is a fail from a session that felt controlled.
Training at exactly 30 WPM
30 WPM gross with no backspace leaves no margin. Error deductions under the 10x formula, exam nerves, and an unfamiliar keyboard can each drop net WPM by 2–4 points. Candidates who train at the cutoff fail at 27–28 WPM net on exam day. Train at 35 WPM gross.
Dismissing half mistakes
Spacing errors, wrong capitalisation, and punctuation errors are 0.5 points each. With backspace disabled, none of them can be fixed. Ten half mistakes add 5 points to total mistakes — the same weight as five full word errors. They consume buffer capacity that could have protected against harder-to-avoid mistakes.
Selecting the wrong Hindi layout at the exam centre
RRB NTPC offers both Remington Gail (Kruti Dev) and Inscript (Mangal) at the centre. Candidates who trained on one and select the other face a session where every key produces the wrong character — with no backspace to recover. Check your admit card for your registered layout and never switch during preparation.
Running only short practice sessions
The no-backspace condition gets harder in the final 3 minutes. Short sessions never reveal this. Candidates who only practise 2–3 minute bursts rush or freeze in the final stretch of a full 10-minute test. Run complete 10-minute sessions every time.
