Girls make boys smarter … A new study from the Netherlands has found that boys get better grades when their classes have more girls in them. Researchers from Utrecht University looked at the reading test scores of more than 200,000 15-year-olds from over 8,000 co-ed schools all over the world, and found that the boys’ scores were higher when more than 60% of their classmates were girls. Why? Researchers theorize that girls not only concentrate better in class but they are also more motivated to read. They believe this has a positive influence on the boys in their classes. (Moneyish)
