HTML Quizzes

Though I've expected that the quizzes could be hard, I haven't studied too much in making HTML's because I've predicted that it would be an open notes quiz because it is too hard for us to memorize all HTML tags and attributes at the same time.  My estimate is that their are about 20+ HTML tags that had been taught to us, how hard it could be if it wasn't an open notes quiz. It is too hard to for me to memorize at least 10 HTML tags because their are still attributes that should come with it. Even though the HTML's given to us was easy to copy, I still thank Sir Tom for that open notes quiz...
