What Are the Best Vocabulary Learning Techniques for IELTS?

2. Spaced Repetition: Scientific intervals (Day 1, 3, 7, 14, 30) Review.

3. Active Recall: Recall without looking at train neural circuits.

4. Collocation Mapping: Raise awareness and solve issues by theme.

5. Word Families: examine, analyse, analytical to analytically.

6. Immediate Use: Speak/write new IELTS band 9 vocabulary list words daily.

7. Shadowing: Fake the native speakers' IELTS speaking vocabulary list fluency.

8. Synonyms: Ladders significant, important, paramount.

Professional Insight: It is pointless to learn a word without its collocations because it is like learning a phone number without the area code; the former is not complete and not applicable in a real IELTS situation.
