How Well Do You Know Harry Potter and the Prisoner of Azkaban?
Let's be real, here, Sparklers: There are far too many good parts of POA for us to ever choose a favorite.
There's Hermione unleashing a righteous fury upon the smirking face of Draco Malfoy. There's Sirius asking Harry to live with him, AKA the moment that Reducto'd our hearts into one thousand Bertie Bott beans. There's the Marauders' Map managing mischief up in Snape's face, and Harry Expecto Patronum-ing a whole mess of Dementors, and Dumbledore asking two underage students to utilize time travel and become low-key felons. IT'S ALL GOLD. It is the most important book in the Harry Potter series, and it is probably the most important book in history.
All of this is to say that it doesn't really matter how well you know Harry Potter & the Sorcerer's Stone or Harry Potter & the Chamber of Secrets. It doesn't matter how many SparkTests you've aced, or how many fanfics you've written, or how many rats you've killed in search of Peter Pettigrew. It doesn't even matter that as a result of your wanton rat-killing, you've become a fugitive from the law in 18 different states and the authorities are, at this very moment, using your SparkLife log-in to track you down and bring you to justice. The only thing that matters, the only thing that will ever matter, is how well you do today.
