Focus on quality: master 8–10 common topics with their collocations rather than memorising long word lists. Being able to use words accurately and naturally matters more than sheer quantity.

High-frequency topic vocabulary

- Adding: moreover, furthermore, in addition
- Contrasting: however, whereas, nevertheless, on the other hand

Golden rule: one wrong collocation is more noticeable than a plain word used correctly. When in doubt, choose accuracy over ambition.
