The short answer
Lexical Resource is about range, precision and natural collocation—not rare or long words.
What it measures
Lexical Resource is 25% of both Writing and Speaking scores. Examiners look at range, precision, collocation, word formation and spelling (Writing) or naturalness (Speaking).
