1600.now

SAT practice built from real past tests. Free, no paywall, no account wall.

Most free SAT sites are lead magnets for a paid course. 1600.now is the opposite: an independent developer took real past SAT material, built a fast interface around it, and gave the whole thing away. It is what we point EconLearn students to when they ask how to prep for the SAT without paying for a class, and it is the backbone of our free SAT prep guide.

What makes it worth your time:

• The question bank: 8,500+ real past SAT questions with one-click filtering by difficulty, topic, time spent, and whether you have solved them before. The filters are the killer feature; you can isolate exactly the practice you need instead of wading through a course.
• 34 full-length practice tests, organized by subject and module, so you can sit a whole test or drill just the harder second math module.
• Step-by-step solution walkthroughs on every question, not just an answer key. Getting one wrong teaches you something instead of just costing you a point.
• 100 Hard Math: a curated set of the questions that separate a 700 from a 780, for students hunting the last 50 points.
• A score calculator that turns raw module results into a projected score, so practice stays anchored to the number you actually care about.

Why we vouch for it: the developer is a friend of EconLearn, and the two sites are built on the same conviction, that the best prep for a standardized exam is high volume on real materials with instant feedback, free. We drill AP Economics graphs; they drill SAT questions. If the SAT is anywhere on your calendar, start with 1600.now and the 6-week plan in our guide.
