Pfft, that's where rumours start from. No, it was not 45 minutes, and no, it was not cheating.
Yes, I hate Ruse haters who hate Ruse for purely no other reason than that they're the best school in the state (academically). Without that extra 15 minutes, they still would've wooped every other school in the state, left right and centre. Contrary to popular belief, they actually do have lives, they actually do go out with each other, and believe it or not, their idea of a muck up day goes beyond tampering with the Maths staffroom's calculators.
