When I was in the 9th grade, I took a test on World War I. I studied pretty well for it. I knew all about the assassination of the archduke, the chain reaction of alliances that caused the countries to declare war on each other, Armistice Day, and the League of Nations. I was pretty sure that I was going to get a 1 or at least a 1- on this test.
My only problem was the name of the U.S. President. I kept referring to him as Wilford Woodruff, not Woodrow Wilson. What kind of name is "Woodrow" anyway? His first name was actually "Thomas." He should have just stuck with that -- it would have saved me a lot of trouble later on. On my test my teacher had underlined and put question marks next to every reference to 4th President of the Church. I think he took off a point for every mistake that I made instead of just counting all similar mistakes as one mistake. That brought my grade down to a 2. However, I haven't made that mistake since then.
