The corpus consists of 1,489 essays written by 440 Swedish university students of English at three different levels, the majority in their first term of full-time studies. The total number of words is 1,221,265, which means an average essay length of 820 words. A typical first-term essay is somewhat shorter, averaging 777 words.
Dowloadable data at http://www.ota.ox.ac.uk/headers/2457.xml
The essays cover set topics of different types. They were written out of class, against a deadline of two to three weeks, length limitations imposed (usually 700-800 words), and suitable text structure suggested. First-term students were admitted for both spring (January 20 - June 6) and autumn terms (September 1 - January 19).
