Cadawalader, relied upon the boy next to hims work, and just copied his work step by step. It was the laziest approach but realistically it was the only one the oldest Selwyn boy could be bothered with. He hated potions at the best of times, it was so boring and slow in comparison to the other subjects. He would drop it as soon as he could. He just needed to get through his OWLs. But it seemed like the Ravenclaw boy beside him was making mistakes and Cad shot him a dirty look as he was forced to fix his own potion because of the others screw up.
