a 2 ( ; when stressed)indef.art. 1. Used before nouns and noun phrases that denote a single but unspecified person or thing: a region; a person. 2. Used before terms, such as few or many, that denote number, amount, quantity, or degree: only a few of the voters; a bit more rest; a little excited. 3. a. Used before a proper name to denote a type or a member of a class: the wisdom of a Socrates. b. Used before a mass noun to indicate a single type or example: a dry wine. 4. The same: birds of a feather. 5. Any: not a drop to drink. [Middle English, variant of an, an; see an1.] Usage Note: In writing, the form a is used before a word beginning with a consonant sound, regardless of its spelling (a frog, a university). The form an is used before a word beginning with a vowel sound (an orange, an hour). · An was once a common variant before words beginning with h in which the first syllable was unstressed; thus 18th-century authors wrote either a historical or an historical but a history, not an history. This usage made sense in that people often did not pronounce the initial h in words such as historical and heroic, but by the late 19th century educated speakers usually pronounced initial h, and the practice of writing an before such words began to die out. Nowadays it survives primarily before the word historical. One may also come across it in the phrases an hysterectomy or an hereditary trait. These usages are acceptable in formal writing. |

A LEVELS
Al terminar la educación secundaria obligatoria, los estudiantes de Inglaterra, Gales e Irlanda del Norte pueden estudiar otros dos años para preparar dos o tres asignaturas más y examinarse de ellas a los 18 años. Estos exámenes se conocen con el nombre de A levels o Advanced levels. Cada universidad determina el número de A levels y la calificación necesaria para acceder a ella.
En Escocia los exámenes equivalentes son los Highers o Higher Grades, que se hacen de unas cinco asignaturas tras un año de estudios. Después se puede optar entre entrar en la universidad directamente o estudiar otro año más, bien para hacer el mismo examen de otras asignaturas, o para sacar los CSYS, abreviatura de Certificate of Sixth Year Studies.
