Then you will learn basic greetings and introductions. After that you will learn very basic conversations on many subjects and in the present, past, and future tenses.
The A1 Level is the foundation of your English learning journey. Like the foundation of a house, this foundation forms the basis of what is to come in the next levels, and sets you on a strong path to speaking to, and understanding, a native English speaking person.
