What this lesson covers

Lesson 9 builds the two skills that distinguish exam-ready typists from practice-only typists: stamina across the full 10-minute test, and the backspace decision — knowing when to correct an error versus leave it.

On stamina: the hardest minute in a 10-minute test is minute 8. Your initial adrenaline has flattened, your fingers are fatigued, and the passage is still going. The fix is daily 10-minute sessions — same passage style, visible timer, no breaks.

On backspace: SSC CHSL allows backspace, but every keystroke costs Gross WPM. The winning strategy: backspace only single-character typos (one keystroke to fix, one error avoided). Word-level errors (typed wrong word entirely) — leave them. The 1-error penalty is smaller than the 5-second recovery from correction.

Drills — type along, do not skip

Full 10-minute passage
10 minutes continuous. Goal: 35 WPM Net, 96% accuracy. Use backspace only for single-character typos.
The Government of India launched the Pradhan Mantri Jan Dhan Yojana to bring banking services to every household across the country. Under this financial inclusion programme, citizens can open zero-balance accounts at any participating bank, receive a basic debit card, and access overdraft facilities once the account remains active. The scheme has helped millions of low-income families build their first formal financial relationship and has made government subsidy transfers faster and more transparent. Direct Benefit Transfer is now the standard method for delivering benefits like the LPG subsidy, scholarship payments, and wages under MGNREGA. Banking correspondents in rural areas have made the programme reach the most remote villages.
Net WPM 0 Accuracy 100% Errors 0
Backspace decision drill
Apply the backspace rule mechanically. Decide in <0.5 seconds.
Apply this rule: if you mistype 1 character, backspace + retype. If you mistype 2+ characters (whole wrong word), leave it. Drill the decision in the passage above.
Net WPM 0 Accuracy 100% Errors 0
Pacing checkpoints
Internalise the pacing. Treat minutes 8-10 as a separate sprint.
Minute 1-2: settle in | Minute 3-5: peak speed | Minute 6-7: hold steady | Minute 8-10: stamina
Net WPM 0 Accuracy 100% Errors 0

Why this lesson matters

The stamina gap is real. Untrained candidates average 38 WPM in minutes 1-3 and drop to 26 WPM in minutes 8-10. Same person, same day. That 12-WPM drop is the cost of insufficient stamina training. Seven days of full-length sessions flattens this to a 3-4 WPM drop.

The backspace strategy is the under-trained lever. Most aspirants treat backspace as either "always correct" or "never correct" — both are wrong. The right answer is conditional: single-char errors yes, word-level errors no. Lesson 9 builds the conditional reflex.
