The core challenge
Part 4 is difficult because it tests argument structure, not just vocabulary. High scorers track claim, evidence, and counterpoint instead of reading line-by-line.
Fast framework
Read question stems first, then scan for thesis lines and contrast markers (however, although, while). This cuts reading load and improves answer precision.
One-week fix
Practice 20-minute Part 4 sets with strict timing and error logs. Focus on two recurring error types: inference misses and near-synonym traps.
