Ribbit builds your study plan from your own answers, then keeps pointing it at the skills costing you the most points. Practice the way the real test asks, and watch the number move before test day.
Your plan is rebuilt from your own answers, so the next session always points at what is costing you the most.
See an estimate of where your 1–36 composite would land today, updated as you work through your plan.
Every question carries a written explanation. Open it the moment you are stuck instead of waiting for a session.
Accuracy and pacing are tracked by section and by skill, so improvement is something you can point at.
Tell Ribbit your starting scores, the composite you want and when you sit the test. It lays out what to do each week and reorders that list every time you finish a session.
Nothing is locked to a syllabus. If Reading catches up and Science slips, the queue follows, and you keep working at the pace your own schedule allows.
Build my planThe bank covers English, Math, Reading and Science across the 43 skills the Enhanced ACT tests, at the difficulty range the real paper uses.
Every item is written against the Enhanced ACT blueprint, then solved blind by three independent checkers before it can reach you. Anything they disagree on gets pulled rather than shipped, and anything that misbehaves in practice is revised or retired.
The practice tests felt so close to the real thing that test day was the least stressful part of the whole year.

Official practice material runs out quickly. Ribbit’s full-length tests run the Enhanced ACT’s real section clocks and are scored by section, so a practice sitting rehearses the same paper you will actually face.
Sitting the whole thing is the only way to rehearse pacing and stamina. Every attempt is logged, so you can compare section scores across tests instead of guessing whether you improved.
Work through a chapter of a book and you finish with a page of answers and no idea what it meant. There is no record, no pattern and nothing that tells you what to open next.
Ribbit scores every session as you go and keeps the history. You can see accuracy by section, which skills are still soft, where your pacing slips, and how your predicted composite has moved since you started.
See your dashboardFour multiple-choice sections, each scored from 1 to 36. Knowing the shape of the paper is the cheapest preparation there is.
| Section | Questions | Time | Focus |
|---|---|---|---|
| English | 50 | 35 min | Grammar, usage and rhetorical choices across short passages. |
| Math | 45 | 50 min | Algebra, functions, geometry and statistics, four choices per item. |
| Reading | 36 | 40 min | Comprehension and inference across prose and paired texts. |
| Science (optional) | 40 | 40 min | Reading figures, tables and short research summaries. |
Science is optional. The composite is the average of English, Math and Reading, rounded to a whole number. Science carries its own 1–36 score and is reported separately, so check whether the colleges on your list ask for it.
Writing is optional too. The essay is a separate 40-minute task with its own score. It does not feed the composite, and only some programs require it. Registration is the moment to decide.
Sit a short diagnostic — 20 questions, about ten minutes. It estimates your starting range and flags the skills holding your composite down.
Enter the composite you are aiming for and the test date you registered for. The plan sizes itself to the weeks you actually have.
Work the queue a few times a week. Weak skills come first, and older skills return on a spacing schedule so they do not slip.
Book a timed test every few weeks. Use the results to check pacing and to confirm the plan is pointed at the right sections.
All three can work. They differ in how quickly they notice what you are getting wrong, and in how often you can reach them.

A good tutor still does things software cannot, and an hour with one costs far more than a month of Ribbit. Plenty of students use both.
I mostly used it on the bus to school. Went from a 28 to a 34 on my December retake. Still kind of surprised.

English was my worst section and it just kept drilling what I got wrong until it stuck. Got a 35 in English. Would recommend it to a friend.

Tutoring never fit around soccer, so he did this on his own without me reminding him. His 33 qualified him for scholarship money we weren't expecting.
