The Great Gatsby is a strong option for learners who already feel comfortable with English and want a more demanding challenge. The vocabulary is not overly technical, though it includes enough variety to make the practice meaningful. At an intermediate level, the main story should be easy enough to follow. At an average of around 86 words per minute, the dialogue is generally manageable, though some exchanges require more attention. If your English is close to B1/B2, The Great Gatsby can be useful for building vocabulary range.
