The math that matters

A 6-point jump can be worth $88,000.

Test scores unlock automatic merit scholarships. At the University of Alabama, a 26 on the ACT earns an out-of-state student $6,000 a year. A 32 earns $28,000 a year.

Up to $88,000 in scholarships over four years, for 14 hours of work. That's the highest-paying job your teen will have before college.

How they work

Simple enough that your teen will actually finish it.

Growth Wise cards drill every rule on the SAT and ACT until it's automatic. 60 minutes a day for two weeks. If the score doesn't jump, you get every dollar back.

Open the box

Numbered, color-coded cards. Every rule and question type on the test, plus the exact 1 to 3 step thought process for each.

60 minutes a day

Use our "4-Deep" and "2-Pile" methods, 5 to 10 new cards a day. Your teen can see measurable progress every single day.

Walk in knowing it cold

In two weeks, the rules are automatic. No guessing, no freezing. Just recognize, apply, move on.

Questions parents ask

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.
