When an owl arrived, he opened the envelope with shaky hands, because he was excited and scared to know, what he received. The school OWLs were listed already with the same grades like the old OWL result, but when he looked, what grades he had received in Latin, warding and spell weaving and crafting. In all three subjects he had received Os. Bill wanted to explode in happiness. He had the OWLs for these three classes, in order to continue for his NEWTs. Bill also saw that his old OWL scores are now invalid since he took three extra classes. For his NEWTs, he would take charms, transfiguration, DADA, potions, herbology, ancient runes, arithmancy, potions, care of magical creatures, astronomy, spell weaving and crafting and warding and furthermore he would self-study history and Latin, since both classes were only theoretical. He quickly wrote to his head of house; in which classes he would continue to go for his NEWTs and which classes he would self-study. With that done, he quickly informed everyone that he had managed his OWLs in the three classes with Os and what classes he would continue to take, what classes he would drop and which classes he would self-study. His father was supportive, but Molly was fuming. Her son had taken those classes that were removed since they were not necessary and now had the grades, in order to become a blasted curse breaker. She needed to talk with Albus, in order to stop Bill from being foolish, but even the headmaster had limited power, because a student could take any NEWTs he wanted and no staff member or even the headmaster could stop, what subjects he or she would take without having the board visiting them.
