Editor's Pick: For middle schoolers prepping for the SAT, this one's enough. It covers 240 functions including trigonometry, statistics, and logarithms, with a two-line display showing input and results to reduce errors. The body comes with a hard shell protective cover, so it can handle being tossed in a backpack. Powered by standard alkaline batteries, no need to hunt for a charging port during exams.
