C is the 15th commonest letter in English prose: 1,241,501 of the 51,993,314 letters in the 111 public-domain books this site cuts its practice texts from — 2.39%, or once every 42. On a QWERTY keyboard it sits on the bottom row, so the left middle finger leaves the home row for it and has to come straight back. The pairs it turns up in most are CO (235,657), CH (227,000), CE (212,631) going out of it and IC (163,254), AC (137,045), NC (127,581) coming into it, so those are the two-key rolls worth getting smooth. In the course it arrives in lesson 12, the C and comma keys.

The pairs it lives in

Two-key rolls are what fast typing is made of: practise the pair, not the letter.
