Warmer Weather During Exams Could Mean Your Child Gets Lower Marks

Warmer weather during the exam period could impact your child's test results, a U.S. study suggests. Researchers found a "significant" link between hotter weather and lower achievement at school.

Researchers at Harvard, the University of California Los Angeles (UCLA) and Georgia State University analysed results of more than 10-million U.S. secondary school students over a 13-year period and found that in years when there was hot weather during exams, the results were lower — and there were better results in cooler years.

The researchers suggested the hot weather made it harder for kids to concentrate on studying in lessons and out of school.
