Aha! Tag at least knew two of the classifications to two creatures. Thanks to himself. He wouldn't mention which creatures, leprechaun and unicorn but he would answer the classification of those.

"Professor I know that XXX means a competent wizard should be able to cope. And XXXX means the creature is dangerous." Tag was rather proud that he knew that right from the back of his head. All those other classifications- eh, his classmates could answer those. "Which means..." Tag started again, clearing his throat now, "That the ministry has classified this leprechaun and unicorn right here as XXXXXXX" He concluded pointing at himself and smirking. That classification wasn't even written down. That's how dangerous he was.
