SSC CGL DEST typing test practice

The DEST requirement in plain numbers

SSC's instruction sheet for the DEST describes a passage of about 2,000 key depressions to be typed in 15 minutes. Everything else follows from that:

A key depression is one keystroke that puts a character on the screen: a letter, a digit, a comma, a space.

Rules are reissued with each CGL notification, including which posts need the DEST, how errors are counted and whether a stricter standard applies to some candidates. Read the notification for your cycle. This site is independent of SSC and doesn't copy its marking scheme.

Who sits the DEST

The DEST is commonly cited as a requirement for Tax Assistant posts in CGL, and some other posts have their own skill tests (a computer proficiency test, for example). The list of posts and their skill tests is set in each notification, so check it there rather than trusting any summary, including this one.

If you were sent here from an SSC CHSL search, the CHSL typing test is a different format: ten minutes at 35 WPM English or 30 WPM Hindi. That has its own SSC CHSL page.

Why 27 WPM is harder than it sounds

On paper, 27 WPM is a modest speed. In a 2018 Aalto University and University of Cambridge study of 168,000 online typists, most people typed between 30 and 60 WPM on ordinary text. The DEST is harder for three reasons that show up on this page too.

The passage isn't a word list. Expect figures, commas, full stops and capitals. On a word test you never leave the letter rows; here you reach for the number row and the Shift keys, and each reach costs time.

Fifteen minutes is long. A one-minute score tells you little about minute twelve. The per-second chart on the results screen shows that drop, and the 15-minute typing test is the right length for full rehearsals.

You type from a fixed passage. The DEST gives you a set text, so you can't skip a hard word. Our test is the same: the text in front of you is the text you type.

How to read your result against 2,000 key depressions

Switch the unit to characters per minute in settings. Then:

• 133 CPM net is the DEST line, if every character were correct.
• 150 CPM net gives you a margin of about 250 extra key depressions over 15 minutes.
• If raw CPM is well above net CPM, you're losing whole words to small errors.

Our net figure is stricter than exam marking: a word with a single wrong character, including a wrong digit or a missing comma, counts for nothing. That's useful pressure for a data-entry test, where the content of a number matters as much as speed. The metrics page has the exact formulas.

You can also compare against the keystrokes per hour test, which reports your result in characters per minute; multiply by 60 for keystrokes per hour, the same unit as the 8,000-an-hour figure in the table.

Setting up a DEST rehearsal here

The page opens on fifteen minutes with numbers and punctuation already on. If you want a shorter warm-up first, the keystrokes per hour test runs one minute with numbers and punctuation on, so the warm-up uses the same kind of text. Tab restarts instantly.

Your personal best is kept for each mode on your device, so a 15-minute best and a 60-second best don't mix. No account is needed for that; signing in only adds history across devices.

Aim for accuracy of 97% or better before you push speed. The board has its own error allowance and we don't copy it, but a candidate who types 140 CPM with many errors is in more danger than one who types 135 cleanly.

Practising the number row

Digits are where a plain-text typist is weakest. A simple plan:

1. Run the numbers typing test a few times and note which digits you miss most on the per-key heatmap.
2. Keep drilling those digits on the numbers test until they're within reach without looking; practice drills are built from real words, so they won't include digits.
3. Go back to the 15-minute test with numbers and punctuation on, and see whether your net CPM holds through the full time.

Use the top number row, not the numeric keypad, unless you know the exam keyboard and software let you use the keypad. Laptops often don't have one, and you don't want to learn a technique you can't use on the day.

Typing from paper

If your DEST passage is printed, your eyes move between paper and screen. That's slower than reading from the screen above your fingers, and it's worth practising once your speed is stable. One simple method: print or copy a paragraph by hand, put it beside your keyboard, and type it into any text editor with a 15-minute timer, then compare it with the original. Our test displays the text on screen, so treat it as the speed and accuracy part of your preparation and use paper practice for the reading part.

Keep your eyes on the source, not the keys. Glancing down at the keyboard between paper and screen is the habit that costs the most time.
