In the Hogwarts universe, Transfiguration is pretty similar to science. You have to get it exactly right or you’re going to mess it up – case in point: remember that time Ron turned his pet rat into that gross furry goblet with a tail? Nobody wants to drink out of that.
“Transfiguration is some of the most complex and dangerous magic you will learn at Hogwarts. Anyone messing around in my class will leave.” – Minerva McGonagall
Sounds an awful lot like when science teachers were drilling us about bunsen burner safety in science lessons…
McGonagall, according to Pottermore, was talented with Transfiguration even as a young student. She was the “winner of the Transfiguration Today Most Promising Newcomer award”, and “under the guidance of her inspirational Transfiguration teacher, Albus Dumbledore, she had managed to become an Animagus; her animal form, with its distinctive markings (tabby cat, square spectacles markings around eyes) were duly logged in the Ministry of Magic’s Animagus Registry.”
So, if you think you’ve got what it takes to pass the science class of the wizarding world, take the test below and see how well you would do in Transfiguration 101!
