Direct answer

Reading and Writing measure different skills. You can recognise arguments in a passage but fail to produce them under 40 minutes with clear position, paragraph unity, and accurate grammar. Reading practice does not automatically transfer to TR/CC; many students over-invest in passages while Writing stays at 6.5.

Key takeaways

Reading and Writing are different skills, high Reading does not guarantee Writing.
TR and CC under time pressure usually explain the lag.
Blind essays with criterion feedback beat more passages.
Fix one TR leak and one CC leak before retesting.

FAQ

Reading is receptive and timed in chunks; Writing is productive, rubric-scored, and penalises TR/CC depth under pressure.

Partially-lexis helps LR but Task Response and Coherence need argument structure, not word recognition.

Map one TR leak and one CC leak on blind essays before more Reading practice.
