Candidate performance 2021

Note: In these sets of data, Nationality and First Language statistics are self-reported by candidates. Nationality may indicate where candidates are currently residing or from where they have immigrated, therefore, it is not an indicator of what language a candidate might speak or their proficiency in English.

Nationality may not correlate to proficiency of the official or common languages spoken in that country. First language is not an indicator of what a candidate’s proficiency in that self-reported first language might be; it also does not take into account other languages that candidate may possess.

Grade information
