What should you answer first before setting a CEFR vocabulary goal?
Start with measurement, not ambition. Most learners misread their active recall level and then over-plan.
How do you estimate a realistic CEFR gap?
Use three signals together:
- Placement Quiz baseline
- Unknown Words concentration
- Review Debt pressure over time
If all three point to instability, your next target should be retention quality before volume growth.
Why vocabulary matters even when grammar is strong
Grammar can structure a sentence, but vocabulary carries precision and speed. Without lexical stability, comprehension remains slow and speaking confidence stays fragile.
A practical 4-step weekly loop
- Calibrate with quiz signals.
- Prioritize red/yellow words in Mastery Flow.
- Reduce Review Debt before adding heavy new volume.
- Track consistency with daily goals and streak.
