Use vocabulary naturally, not forcefully
Vocabulary Upgrade Example
Basic:

Small changes = big improvement.
Technique 1: Word Replacement Strategy
Instead of using basic words repeatedly:
- Replace with simple academic alternatives
- Keep meaning clear
Technique 2: Collocations (Natural Word Pairs)
Use words that naturally go together:
- make a decision

- provide support
This improves natural fluency

- Use same word repeatedly
- Force advanced words
Balance is key
