Why this test matters
RRB NTPC document-verification typing is where many railway aspirants stumble, because the scoring is unforgiving in a way raw-WPM tools never reveal. The board forgives roughly the first 5% of mistakes, then deducts ten words for every mistake beyond that — so a handful of uncorrected errors can erase a comfortable-looking speed. There is also a hard minimum: type fewer than about 300 words (English) and you are disqualified outright regardless of accuracy. With Backspace disabled, you cannot dig yourself out. Practising against this precise formula, rather than a generic timer, is the difference between a confident pass and a surprise rejection.
