Fred and George were not really interested to learn and research, but they were going to use the subjects to their advantage for their products and their business. Both twins planned to take arithmancy and ancient runes, in order to get into warding and spell crafting and weaving. In that way, they would be able to learn the family magics on both sides of the family. They were also planning to go into alchemy, laws and muggle studies. Alchemy was a class to use, so that they could create their own elixirs for their prank products. Laws would be necessary, in order to know their rights, if they were facing lawsuits and any other problems with the law without hiring an expensive barrister and muggle studies could be used to turn muggle prank products into magical prank products. They would also continue in Flying, in order to have fun and be ready for quidditch.
