Before you order
How does the guarantee work?
Have your teen use the cards 60 minutes a day for 14 days. If their score doesn't rise by at least 10 ACT English points or 100 SAT verbal points (Grammar), or 6 ACT composite points or 200 SAT points (Complete Bundle), email us at info@growthwise.us and we refund you in full.
The test is in three weeks. Is it too late?
No. The method takes 14 days. That's exactly why it works: it's finite, so your teen can actually finish it before test day.
SAT or ACT? Does it work for the digital SAT?
Both. The cards cover the rules and question types shared by the ACT and the digital SAT.
My teen won't study. Will they really use this?
These cards are numbered, so your teen sees progress every day and knows exactly when they're done. And there's no phone involved.
Which one should I get?
If you want the biggest overall jump, get the Complete Bundle. If English or grammar is the weak spot, start with Grammar. It's our top seller and the fastest section to raise.
Can we get extra support?
Yes. Our 1-on-1 tutors are experts in these exact cards and pair perfectly with them. Email info@growthwise.us to talk with a tutoring specialist.
Worst case, you get every dollar back.
Best case, thousands saved on college.
Have your teen start tonight. 14 days from now, they walk in knowing every rule cold.
