Courses for adults

• Basic English (levels A1.1 to A1.4): for beginners, and anyone starting again from the basics.
• General English: for steady progress in speaking, listening, reading and writing.
• Advanced English: for confident speakers who want fluency and precision.
• Business English (levels B2.1 to C1.4): for professionals who use English at work.
