   3 flagged findings: an Arnsten quote with a journal-name inconsistency (Nature Reviews Neuroscience in text vs Trends in Cognitive Sciences in the article's own references); an implausible heart-rate upper bound (160 bpm, more associated with vigorous exercise than seated test anxiety) presented as a typical exam-anxiety range; an unverified '15-30%' gastrointestinal-symptom prevalence stat with no citation.

   Before

   Test anxiety activates the sympathetic nervous system, producing: elevated heart rate (60-100 bpm rising to 100-160 bpm)... ||| "The prefrontal cortex -- responsible for working memory, planning, and inhibition of inappropriate responses -- is exquisitely sensitive to stress hormones. Even moderate cortisol elevation measurably impairs the cognitive functions that underlie academic test performance." -- Arnsten, Nature Reviews Neuroscience, 1998 ||| Pre-exam nausea and gastrointestinal symptoms are common -- studies suggest 15-30% of test-anxious individuals report regular gastrointestinal symptoms before exams.

   After

   Test anxiety activates the sympathetic nervous system, producing: elevated heart rate (rising noticeably above a normal resting rate)... ||| The prefrontal cortex, responsible for working memory, planning, and inhibition of inappropriate responses, is exquisitely sensitive to stress hormones. Even moderate cortisol elevation measurably impairs the cognitive functions that underlie academic test performance, a relationship documented in Arnsten's research on catecholamine modulation of prefrontal cortical function. ||| Pre-exam nausea and gastrointestinal symptoms are common among test-anxious individuals.

   Why: De-attributed an Arnsten quote and corrected the citation framing to match the article's own reference list, which correctly cites Trends in Cognitive Sciences rather than the unverified Nature Reviews Neuroscience. Softened an implausible heart-rate upper bound (160 bpm, more associated with vigorous exercise than seated test anxiety) presented as a typical exam-anxiety range.

   Removed an unverified 15-30% gastrointestinal-symptom prevalence statistic with no citation, keeping the qualitative claim.
