Complete the university's degree requirements. The traditional path for college undergraduates takes four years of full-time study. Some students complete their Bachelor of Science degree in three years. Each university or college will have its own degree requirements. Tulsa University in Oklahoma, for example, offers a traditional four-year program, but allows students to complete their degree in less time if they have completed relevant coursework elsewhere.
