Here's why:
* Sixth Form: In the UK, sixth form refers to the final two years of secondary education (Years 12 and 13), after GCSEs and before university.
* Classe de Première: In France, this is the second-to-last year of secondary education, corresponding to Year 12 in the UK.
It's important to note: There is no direct equivalent to "sixth form" in French, as the educational system is different. However, "classe de première" is the most accurate translation for the concept of the final two years of secondary education before university.
