On a computer-delivered Writing test you type Task 2 and a word count is visible on screen. The minimum is still 250 words; 260–290 is a practical range so you are not counting by hand. Use the count as a finish check, not as a scoreboard in minute five. If you watch it while you write sentence one, you stall and the last paragraph dies. Plan 5, write 30, check 5. Cut, copy, and paste can fix order, but they do not help if you never reach the conclusion. Practise a full typed essay in 40 minutes so backspace does not eat the clock. Practice IELTS is a computer Writing and Reading tool. It is not the official familiarisation test, not a booking page, and not Listening or Speaking.
