That is very strange enuf. On another note, how did you get 100% lol? I don't have a grade yet, and guess I won't for a bit. My TA I had is in NY doing disaster relief for the red cross.
Once they gave us full credit for the quizzes the rest was doable for me. APA for the most part, has not been a problem for me. Most likely because I have been exposed to classes at a university that was very heavy on APA, but of course the 5th edition and not the sixth.
I have also learned that no matter how you answer questions, the important piece is to justify why you arrived at this conclusion.
Lastly, I am an anal writer. Since the rules often change, I never turn in assignments until the weekend so I can make corrections according to any new "rules" that pop up during the week. Even if my paper is finished on Monday, I would not submit until Saturday, at the earliest. I read my paper several times before submitting. I spell and grammar check it to death.
Now, if the class was based solely on tests, I'd be in trouble. I am a horrible test taker especially with timed tests!
