AI ACT Tutor, built for the Enhanced ACT

Most ACT prep is still scoring a test that no longer exists. PrepGraph is an AI tutor for the ACT built on the current test: 40 scored English questions, 41 Math, 27 Reading, and a composite that averages English, Math and Reading only — Science is optional and does not count. It finds the question types costing you points, explains them step by step at whatever hour you study, adapts what it gives you next, and pushes your time toward the section actually dragging your composite down. Free to start, no credit card.

Start free → Score a practice test first

Why this matters. The ACT changed. Only 40 English, 41 Math, 27 Reading and 34 Science questions are scored — the rest are unscored field-test items — and the composite is now the sum of your English, Math and Reading scale scores divided by three, rounded half up. Science is excluded. Prep built on the legacy four-section test will point you at the wrong section, and a calculator that divides by four will hand you the wrong number. Everything on this page, and in our ACT score calculator, uses the official Enhanced ACT tables.

How it works

1

Start with a real number, not a guess

Score a practice test with our free calculator, or take a diagnostic inside PrepGraph. Either way you begin with an honest composite out of 36 and a section-by-section breakdown of where the points are actually leaking.

2

Set your target composite

Tell PrepGraph the composite you need for your target colleges. It works backward from that number into a personalized study plan, and shows a score prediction so you know where you stand before test day rather than after it.

3

Practice the question types you keep missing

The tutor identifies your weak question types and drills those, instead of redrilling the material you have already mastered. Practice is timed and section-accurate, with adaptive difficulty and pacing feedback.

4

Get unstuck the moment you are stuck

Hit a wall at 11 p.m. and you can ask the AI tutor about that exact question and get the full solution walked through, step by step. Then it checks whether you can do the next one on your own.

What the AI tutor actually does

Concrete capabilities, not adjectives. Every item below is a feature that ships on the plan.

Built on Enhanced ACT scoring

English 40, Math 41, Reading 27, Science 34 scored questions. Composite is the average of English, Math and Reading. Your practice, your score prediction and our calculator all use the current test, not the retired 75/60/40/40 one.

Diagnoses weak question types early

Not "you are bad at Math" but which question types are costing you points across English, Math and Reading, so a study session has a target instead of a vibe.

Explains first, then tests you

When you are stuck, the tutor walks the whole solution rather than only asking Socratic questions back at you. Once the method lands, it hands you a similar question to prove you can run it yourself.

Voice Learning

Talk a problem through out loud with the tutor. Useful for Reading and for Math setups where writing out your confusion is slower than saying it.

Mastery Loops

Adaptive spaced revision that resurfaces the concepts you got wrong, at the point you are about to forget them, rather than letting them quietly rot until the week of the test.

Unlimited exams, quizzes and assessments

No cap on practice sets, quizzes or full assessments on a paid plan. (AI tutor conversations run on a monthly credit allowance — see pricing.)

Composite-aware prioritization

Because your composite averages three sections, your weakest one drags it down harder than your strongest one lifts it. PrepGraph pushes your time toward the section that moves the average.

Performance Analytics and a parent dashboard

Progress tracking by section and question type, plus an optional parent dashboard with weekly reports — so the check-in conversation is about data instead of guesswork.

One subscription, every test

SAT, ACT, AP and K-12 (Common Core) are all included. If you are still deciding between the SAT and the ACT, you do not have to buy twice to find out.

A note on honesty: AI tutor conversations run on a monthly credit allowance that refreshes every month, sized for a serious daily study routine. We do not call it “unlimited AI tutoring,” because it is not. Exams, quizzes and assessments genuinely are unlimited.

How we compare, honestly

We publish an open comparison of AI ACT tutors whose whole purpose is to help you pick the right tool even when that tool is not ours. This is the short version. We are not claiming to be the number one pick, and where a competitor is better we say so.

Khan Academy / Khanmigo

Free / ~$4 per month

Where it wins: Free, official, and hard to beat on price. Khanmigo runs about $4/month.

The trade-off: No dedicated ACT course — Khan Academy is the College Board’s SAT partner, and its strength is the SAT. Khanmigo is also deliberately Socratic: it guides with questions rather than showing a worked solution. That is a real strength for building independence, and a poor fit for the nights when you are stuck and want the method shown to you.

Acely

~$49 per month billed annually

Where it wins: Genuinely feature-dense. Both tests in one subscription, a large question bank and a lot of full-length tests, with a 24/7 AI tutor.

The trade-off: More features than PrepGraph, and we will say so. A credit card is required for the 72-hour trial, and we are at price parity with it rather than undercutting it.

UWorld

~$19–49 per month

Where it wins: The best detailed, illustrated explanations in the category. A strong specialist if explanation depth is the thing you are missing.

The trade-off: ACT is sold separately from SAT, and it is a question bank rather than a tutor that plans your week for you.

R.test

Free tier available

Where it wins: Fast adaptive diagnostic — a score estimate in roughly 40 minutes. It diagnoses faster than we do.

The trade-off: It is a diagnostic, not a daily tutor. You will still need something to do the teaching afterward.

LearnQ (Mia)

Free tier, paid plans vary

Where it wins: Conversational and gamified, with a free tier and a diagnostic. Pleasant to use daily.

The trade-off: SAT-led, with limited ACT coverage — which matters if the ACT is the test you are actually taking.

Princeton Review / Kaplan

~$300–$3,000+

Where it wins: Structured courses with live human instruction and a long track record.

The trade-off: Priced at roughly $300 to $3,000-plus. That is the gap we compete in, on cost and on adapting to you specifically.

Competitor pricing is approximate and current as of 2026 — check each provider’s site before you buy. Whatever tool you pick, take official full-length ACT practice tests from ACT itself. No AI tutor, ours included, is a substitute for sitting the real thing under real timing.

Where PrepGraph is the better call

  • You want the current test. We are built on Enhanced ACT scoring, including a composite that excludes Science.
  • You get stuck and want the answer explained. We walk the full solution rather than only asking you questions back.
  • You have not committed to the ACT yet. One subscription also covers the SAT, AP and K-12, so you are not buying twice.
  • You are pricing against a human tutor. US ACT tutoring runs roughly $50–150 an hour. One hour costs about what a month here does.

Frequently asked questions

What does an AI ACT tutor actually do?

A good one does three things a question bank cannot. It works out which question types you are getting wrong, it explains a problem you are stuck on step by step at whatever hour you are studying, and it changes what it gives you next based on what you just missed. PrepGraph does all three, and prioritizes the section that is dragging your composite average down.

Is PrepGraph built for the Enhanced ACT or the old one?

The Enhanced ACT, which is the current test. Scored questions are English 40, Math 41, Reading 27 and Science 34, and your composite is the average of English, Math and Reading only. This matters more than it sounds: a lot of ACT prep material and a lot of score calculators still assume the retired 75/60/40/40 test with Science in the composite, and will give you a number for a test that no longer exists.

Does the Science section count toward my ACT composite?

No. On the Enhanced ACT, Science is optional and is excluded from the composite. It still produces its own 1-36 scale score and feeds the STEM score (the average of Math and Science), and some colleges, scholarship programs and state testing requirements still want it. Check what your target schools ask for before you decide to skip it. PrepGraph covers Science either way.

Is there a free AI ACT tutor?

Partly. PrepGraph has a free plan that is free forever, with trial credits at signup and no credit card required, and our ACT score calculator and score planner are free with no login. Khanmigo is about $4 a month and is excellent value, though Khan Academy has no dedicated ACT course. If free is your hard constraint, start with the free tools and the free tier and see how far they take you.

How much does PrepGraph cost?

The Student plan is $50 per month in USD, or $540 a year (list $600, with a 10% annual discount, which works out to about $45 a month). Payments run through Stripe, you can cancel anytime, and you keep full access to the end of the billing period. The free plan stays free with your progress saved. One subscription covers the ACT, the SAT, AP and K-12.

Can an AI tutor replace a human ACT tutor?

For most students, for most of the work, yes — and the math is not close. Private ACT tutoring in the US runs roughly $50 to $150 an hour, so a single hour costs about what a month of PrepGraph does. Where a human still wins: if you need accountability from a person who will notice you skipped a week, or you have a specific learning difference that needs a specialist, hire the human. We would rather tell you that than sell you the wrong thing.

Do you guarantee a score increase?

No. We do not offer score guarantees, and we would be suspicious of anyone who does. We have not published score-gain statistics because we do not have verified ones, and inventing them is not something we are willing to do. What we will do is show you your predicted score and your progress by section, so you can judge for yourself whether it is working.

What if I have not decided between the ACT and the SAT yet?

Then do not buy two subscriptions. PrepGraph covers the SAT and the ACT (and AP, and K-12 Common Core) on one plan, so you can practice both, compare where you naturally score better, and commit to one without having paid twice for the privilege.
