A chapter on clear e-mail communication and etiquette is brand new in this edition, as are many of the author’s challenging “Brain Ticklers.” Her helpful chapter on how to edit a school paper has also been heavily revised and updated. Barron’s popular Painless Series of study guides for middle school and high school students offer a lighthearted, often humorous approach to their subjects, transforming details that might once have seemed boring or difficult into a series of interesting and mentally challenging ideas. Most titles in the series feature many fun-to-solve “Brain Tickler” problems with answers at the end of each chapter.
