The CEFR categorizes language proficiency into six levels, A1–C2, which can be further subdivided based on the needs of the local context.
Levels are defined by 'can-do' descriptors. The levels did not appear out of nowhere in 2001, but rather evolved over time, as described below.
Memoir vs Autobiography-
Memoir comes from the French word mémoire, this means that memory. A memoir is a nonfiction however subjective series of narratives wherein the writer recalls experiences, emotions, and activities from a sure length of their life. Memoirs cognizance on in detail conveying their notion of those reminiscences in a manner that is emotionally straightforward however isn’t fact-checked whereas an autobiography is a nonfiction account of someone’s existence that they wrote themselves. Usually, an autobiography covers the writer’s whole existence as much as the factor of writing in chronological order and is sometimes (even though now no longer always) drafted withinside the later years of the writer’s existence. The occasions stated in autobiographies are real and fact-checked. They’re frequently used as sources through historians.
Based on these accomplishments, the CEFR has developed a description of the process of mastering an unknown language by type of competence and sub-competence, using descriptors for each competence or sub-competence, which we will not go into further detail here. These descriptors were developed without regard for any particular language, ensuring their relevance and universal applicability. The descriptors describe each skill's progressive mastery, which is graded on a six-level scale (A1, A2, B1, B2, C1, C2).
