This is a good idea. It is not redundant, for it is more comprehensive than the other quizzes on this subject. But, you have serious problems that must be fixed. It is not even worth taking this quiz until you do. These flaws include misspellings (cf. "potrait", "pervious", "head quarters"), missing capitalizations of proper nouns (cf. _O_rder of the Phoenix, Care of Magical _C_reatures, etc.), inconsistent formatting (cf. capitalization of words in parentheses), awkward phrasing (e.g., reference books, dates, or 'generational era' as in Riddle Era or Post-Epilogue/2nd Generation Era instead of Tom Riddle, Harry's children, et al.), jargon (cf. the lack of full names of classes), and failure to indicate in the instructions that names can and will be used more than once.
