Your Teen's SAT Grammar Score Rises 100+ Points — or You Pay Nothing
The same flashcard system used by students who went from the 20s to 35+ on ACT English. 90 cards. Real score jumps backed by a money-back guarantee.
🛡️ 14-Day Guarantee: 10+ point ACT English rise, or 100+ SAT Verbal rise, or your money back.
Why Most Test Prep Doesn't Move the Score
The "Pretend Test Prep" Trap
99% of test prep is the same loop: take a practice test, review wrong answers, repeat. It never systematically builds the knowledge base you need. Students spend months (and thousands of dollars) barely moving the needle.
What Actually Works
Our flashcards give you every grammar rule, every question type, and the exact thought process for each one — all in a single box of 90 cards. No guessing. No gaps. Suddenly, the amount you need to learn is finite and manageable. Every card memorized feels like a win.
The flashcards put me at such an advantage during the Grammar section. My friend sitting next to me just looked so stressed and she's been tutoring for four months. They really burned everything into my mind.
Here's Everything Inside the Box
- 90 flashcards numbered and color-coded by theme — the definitive list of grammar rules for a perfect SAT/ACT score
- Every question type on the SAT and ACT grammar sections, with the exact 1-to-3-step thought process for each
- Test anxiety toolkit: techniques to bring the best version of you to test day
- Optional 1-on-1 tutoring with experts in the cards — accountability, personalized guidance, and Q&A
- Free Zoom onboarding call with Jack to get oriented on how to memorize the cards and apply them
- Money-back guarantee: 10-point ACT English rise (or 100-point SAT Verbal), or a full refund
My daughter said your flashcards were the best and what raised her score the most. I bought her all of the SAT materials out there — the Shark Tank guy's course, all the workbooks on Amazon we could find.

From 22 to 35 on ACT English:
Patrick's Story
Patrick was a sophomore scoring a 22 on ACT English — 48 right, 27 wrong.
His first two weeks? No movement. He admits he was cutting corners on the memorization method.
Once he tightened up and fully applied the method, his score shot up: 28 by April, 32 by May, 34 and 35 in June.
His advice: "Just keep doing them. Even if you're only getting three or four of the 90 cards correct early on, you can still make progress."
Money-Back Score-Raise Guarantee
Use our memorization methods. Study the cards and take practice sections for 60 minutes per day for 14 days. If your ACT English doesn't rise by 10 points (or SAT Verbal by 100 points), we give your money back. No questions asked.
Parents and Students Are Seeing Real Results
My son studied these cards over the course of the week leading up to the June 3rd SAT and his verbal score increased 110 points! We are so thrilled!
Just wanted to let you know my score. I got a 35. I studied for about 3-4 days leading up to it for like 2 hours a day. It worked!
It was just big jumps. Once I started to see which rules were being tested, I was able to jump all the way up.
Elle is very happy with the cards and your approach. She told me that she wished she had done this all along.

Frequently Asked Questions
How does the money-back guarantee work?
Study the cards using our memorization methods for 60 minutes per day for 14 days. If your ACT English score doesn't rise by at least 10 points (or SAT Verbal by 100 points), contact us for a full refund. No questions asked.
Aren't flashcards old-school? Why not an app?
That's exactly why they work. Physical flashcards enable deep, focused attention — no YouTube, Snapchat, or text notifications interrupting you. You get to fail and retry rapidly, which is how real memorization happens. As one student put it, "they work like magic."
Will these help with both the SAT and ACT?
Yes. The 90 cards cover every grammar rule tested on both the SAT Verbal and ACT English sections. The question-type training applies to both tests as well.
What if my teen is already doing test prep?
Most test prep involves taking practice tests and reviewing wrong answers — what we call "pretend test prep." Our flashcards complement any existing prep by building the foundational knowledge base that practice tests alone can't build. Many of our best success stories come from students who were already in other programs.
Do you offer tutoring with the flashcards?
Yes! After purchase, you can book a free Zoom call with Jack to get oriented. From there, optional 1-on-1 tutoring is available with tutors who are experts in the card system. They'll hold your teen accountable and give personalized guidance.
How quickly do students see results?
Most students see measurable score increases within the first 14 days. Some see dramatic jumps in as little as a week — like Susan's son who went from a 29 to a 34 after just one week of studying, or Mila who scored a 35 after 3–4 days of focused practice.
Don't Let Another Test Go By
Every month you wait is another practice test your teen takes without the right foundation. The cards are ready. The guarantee removes the risk.
