The document discusses conversational English groups at the University of Nebraska Medical Center. It notes that the groups aim to help students improve their English proficiency through informal conversations, which can help with exams like TOEFL and IELTS. The groups discuss topics like the differences between American and international English and how language is best learned through informal practice and observation rather than only formal classroom settings. Joining the conversational groups can help students learn English with fun, make connections, and better prepare for work or studies in the United States.
