About SAT Study Toolkit
SAT Study Toolkit is a free Chrome extension that adds the digital SAT's Bluebook-style tools to any website: a 3-color highlighter, strikethrough to eliminate answer choices, sticky notes, a graphing calculator, and a countdown timer. Practice on any article, PDF, or prep site with the same tools you get on the real test, so nothing feels new on exam day. Completely free, no account needed. Built by a student who scored 1520.
