These
thematic graded
crosswords and other puzzles have been designed for
students of
English
as a foreign or
second language, at advanced and intermediate levels. They are
particularly aimed at
students in the final years of high school or in further education
(years 8 to 12 - sixth forms or adult learners) .
Designed to develop or test vocabulary in specific fields, they
generally use British English spelling (where it differs from
American English), and were originally designed for students in
European high schools. Puzzle pages are not optimized for viewing on
