an unsuccessful attempt at at the end of their , students are allowed to repeat that second year once or even twice. This means that students can remain in the whole programme from two up to four years in total (see also the section on slang terms). For the vast majority of students who will fail to get selected to ENS, having merely attended a curriculum remains valued per se on the job market, even though it provides no formal degree. Current organisation of the khâgne program There are two kinds of hypokhâgnes: 1) The hypokhâgne A/L which can either lead to a Khâgne Ulm or a Khâgne Lyon. 2) The hypokhâgne B/L which leads to the Khâgne B/L only. There are therefore three kinds of khâgnes: khâgne B/L, khâgne Ulm, and khâgne Lyon, respectively preparing to the following entrance exams: The entrance examination (A/L section) to the ENS Ulm The entrance examination (A/L section) to the ENS of Lyon. The entrance examination (B/L section) to the ENS Ulm, the ENS of Lyon and the ENS Paris-Saclay Khâgnes de Lettres (Ulm and Lyon) The two remaining kinds of khâgnes are literary khâgnes: khâgne Lyon and khâgne Ulm. Khâgne Ulm prepares to the A/L section of the entrance examination to the ENS of Paris. As the khâgne B/L, the particularity of the khâgne A/L lies in the fact that curricula of some subjects is unlimited. Each subject of the entrance examination must be taken in a written and in an oral form. The six written subjects taken are given the same coefficient: a codified essay in French literature, in history and in philosophy, a translation from an ancient language, a translation from a modern language and a commentary of it, and a subject taken as a speciality. During the oral entrance examination, the literary analysis of a French literary text, an examination in philosophy, in modern and in ancient languages are based on an unlimited programme, and so is the extension of the curriculum in history. However the examination in the subject taken as a speciality is based on an explicit curriculum. About 2,000 students attend the khâgne ulm. Khâgne Lyon. It prepares to the ENS of Lyon, which is more recent than the ENS Ulm, though it is better ranked in some research departments such as in exact and experimental sciences. Each subject taught is based on an explicit curriculum
