Student testimonials.
“RibbitEDU genuinely is a lifesaver, I am a highschooler senior and it took me from a 33 to a 36 in 2 months, I feel so much more confident about my applications now!”
Logan S.“SAT Prep used to feel so hard without a centralized prep plan, but thanks to RibbitEDU, I feel more confident about my SAT”
Pranay R.“The biggest difference for me was feeling like I had a place to start. RibbitEDU made prep feel more manageable, and I stopped dreading every study session.”

Frequently asked questions.
What is RibbitEDU?
RibbitEDU is your AI-led ACT/SAT instructor. A curated algorithm reads your skill levels, builds your custom plan of attack, and serves practice that adapts to your performance with every question across the sections of your chosen test. Everything runs in the browser. Nothing to install, nothing to schedule.
How does the Rapid Diagnostic™ work?
Choose your test and answer 12 questions calibrated as you go. The ACT/SAT diagnostic takes about 10 minutes. At the end you get an estimated overall score, a section-by-section breakdown, and the skills to focus on next — plus a customized study plan. It's free for a limited time.
How much can my score improve?
Your ACT/SAT improvement depends on your starting point, practice, and time before test day. RibbitEDU uses your diagnostic to focus practice on the skills you need most, then adapts as you improve. Student results are individual examples, not a promise of a particular score.
Why RibbitEDU instead of a tutor?
Families spend about $2,250 on tutoring for one student's structured plan. RibbitEDU's algorithm does the same job — plans, targets, re-plans — and re-reads your level after every single question, which no weekly session can. From $33 a month, whenever you have 10 minutes.
Is it really free to start?
Yes. The Rapid Diagnostic™ — your score estimate, full breakdown, and custom plan of attack — is completely free for a limited time. You see exactly where you stand before you decide anything.
Ten minutes a day — seriously?
Seriously. Ten focused minutes on your proven weaknesses beats hours on the wrong material. The algorithm decides what those minutes hit; you just show up. More time helps — but it's never the entry price.
Can I cancel?
Any time, from Settings. You keep access through the period you already paid for — cancelling on day two of a month you bought does not cut you off on day three.
Do you store my card?
No. Stripe handles the payment and holds the card details; we never see or store your full card number.
Is there a refund policy?
Email us. If RibbitEDU is not doing what it says, we would rather refund you than argue about it.
