OUR MISSION
Can I cancel anytime?
Yes, 100%. You can cancel your subscription at any time with just a few clicks. When you do, your plan will not auto-renew, and you will keep full access to all Linus features for the entire remainder of your billing period (either the rest of the month or the rest of the year you've paid for). No hassle, no hidden fees.
How are Linus questions and tests made?
No AI slop here, guaranteed. We use AI as a tool, but the real magic comes from our human experts—every one of our thousands of questions (and growing) is meticulously written and vetted by our perfect-scoring content team (no 1590s allowed). And since Linus was built from the ground up exclusively for the new Digital SAT, our questions aren't just 'adapted' from an old textbook. They are a perfect match for the real exam's format, style, and difficulty.
How accurate are your tests?
Incredibly accurate. We are confident that a score you earn on a Linus practice test would be within ±20 points of your official College Board score. We’ve meticulously 'blueprinted' the real exam's adaptive logic and structure. The only tiny variable we can't account for is the College Board's secret test-day curve (hence the 20 point variance), but we've gotten as close as humanly (and algorithmically) possible.
How does the Linus Score Predictor work (and why is it so accurate)?
Forget comparing you to random past learners—that's just guessing. Our predictor uses the real Digital SAT's scoring DNA. Every single question you answer in Linus (lessons, drills, tests, everything) feeds our model, constantly refining its precision based on your unique performance across all skills and difficulties. The more you prep, the smarter, tighter, and more reliable your prediction gets.
Is gamified learning effective?
Absolutely. It’s not just a gimmick, it’s a scientifically better approach. The key to a high score is consistent practice, which is why our core loop is built to be rewarding: Practice a concept -> Get instant feedback -> Earn rewards -> Practice more. These gamified elements (streaks, daily quests, leaderboards and more) provide the extrinsic motivation to build a daily habit you'll stick with. We also use associative learning (our colorful characters!), a technique shown to boost memory retention by 25%.
Why should I pay for Linus if Khan Academy is free?
Great question! We're huge fans of Khan Academy—it's an amazing, massive free library. But that's just it: it's a library of content. Linus is a product laser-focused on one thing: getting you a higher SAT score. Our platform is hyper-personalized to your specific needs, whether you're just starting or already at 1500+. We're not a pile of 'one-size-fits-all' videos; we're an adaptive, gamified system (with 4.9-star mobile apps!) designed to build a daily study habit that delivers real results.
Is Linus for long-term study or last-minute cramming?
Both. We're built for your timeline, whether you're a long-haul marathoner or a last-minute crammer. Got time? Our structured Study Paths guide you step-by-step, like a gamified map, building your skills at a steady, low-stress pace. Need to cram? Go for it. You can "binge" our full-length adaptive tests, drill only the skills you need with Targeted Practice, and fast-track your learning with our expert explainer videos. Either way, it’s the same simple, affordable subscription for full access. We're ready when you are.
What if I'm already a high scorer?
Linus is built for you. We have thousands of questions calibrated perfectly to the College Board's highest difficulty levels. Our "Targeted Practice" feature lets you filter and drill only Hard questions in the specific skills you need to perfect. Even better, we have a unique feature that lets you practice only the hard Module 2—letting you focus all your energy on the toughest content. You won't waste a minute on questions you've already mastered.
Is Linus available as an app?
Is it ever! We're one of the only SAT prep platforms with true, native mobile apps for both iOS and Android—and frankly, they’re fantastic. You can prep anytime, anywhere, with your progress synced perfectly across devices. Oh, and our learners seem to agree: we're rocking a 4.9 on the App Store and a 4.8 on Google Play.
Is Linus available for educators?
Yes! We partner with schools, tutors, and non-profits to bring smarter, more effective prep to their learners. We offer affordable group pricing for any size program and provide admin dashboards to track progress. We're on a mission to improve educational equity, so if you're an educator—especially if you're with a non-profit—please get in touch. We want to help!
Who is Professor Linus?
Ah, a splendid inquiry. Professor Linus is our resident SAT genius and mascot—a banana slug with a (dare we say) sardonic wit and a mind for math. He's the inspiration for our entire teaching philosophy! Very soon, he'll be making his debut inside the app as your personal AI tutor. And... psst... he's also the world's first real-life, AI-powered plushie tutor. Check him out in our Shop!
I have a question you didn't answer...
