England go into Tuesday's final Group A game against the West Indies at the Women's World Cup knowing that a win will guarantee their Super Six place.
Both sides, along with hosts India and Sri Lanka, are all on equal points with a win each from two matches.
The winners of Tuesday's games will advance while net run-rate will decide which of the two losing sides progress to the next stage.
England are currently third on net run-rate behind West Indies and India.
Captain Charlotte Edwards' side beat the Windies 4-1 in a T20 international series in September but know that they need to be wary of batters Deandra Dottin and Stafanie Taylor who have been in superb form already this tournament.
Taylor hit 171 in her side's 209-run win over Sri Lanka on Sunday while Dottin has smashed 89 from just 38 balls in the competition so far, including eight sixes
"They have got two world-class players in Stafanie Taylor and Deandra Dottin. We're very aware of both of them and we have our plans in how we want to bowl to them. We're not going into it blind," said England bowler Katherine Brunt.
"We know exactly what we want to do and we're really confident. We've got a lot of wins against them in comparison to losses, so we're really confident and hopefully we can execute our skills."
