Expert writing Tips
Best practice
Always double-check the article (a, an, the) before "class of" to ensure correct grammatical structure and meaning. Using the correct article, such as "the class of" or "a class of", ensures clarity and grammatical accuracy.
Common error
Avoid using possessive pronouns like "he", "she", or "they" instead of articles such as "the" or "a" before "class of". The correct form typically requires an article to specify or generalize the class being referenced.
