You should have more variations, English and Japanese names. For instance I got caught out on Ao no exorcist, as I said Blue exorcist. Plus you should put the date at which you're taking this chart from. Since the anime chart changes often. At present when you're taking the test you have to try and guess what would be out at the time you created it. Especially with the sequels, you aren't specific about if you count them or not.
According to who? When? Some of these seem weird. I would think Cowboy Bebop is more well known than Samurai Champloo. And Naruto Shippuuden is the same thing as Naruto as far as I'm concerned.
