Writting a 6 page essay about an event that happened after 1900. I chose Alan Turing and his invention, the computer and how he helped Britain win against Germany in world war II. Currently I have an A in this class, but because I will be turning this paper late it will be graded on 90 points instead of 100, so I need a great grade!
