What is wrong here?
The violin and the cello sounds beautiful together.
Two subjects joined by and are plural and take a plural verb, unless together they name one single thing.
Better: The violin and the cello sound beautiful together.
Count the subjects before the verb: this and that together equal they.
Fix the underlined part
As rain falls through the air and soaks into the soil, it picks up carbon dioxide. Rainwater and carbon dioxide combines to form carbonic acid, a weak acid that can slowly dissolve limestone.
That was one rule card and one question.
A study day also has 15 new words, a second rule card, the rest of an English passage and a Reading set. This sample comes from the free set and saves nothing.

Everything for ACT English and Reading, and nothing else
What you would be paying for
Rule cards
124 rules in teaching order: punctuation, agreement, transitions, concision and more. Each shows a wrong sentence, the rule and a better version.
Word cards
600 academic words for high-school reading and word-choice questions, with meaning, example, pronunciation and root.
English practice
730 practice questions in 73 passages. Every question has a rule, an explanation and a note on each wrong choice.
Reading practice
603 practice questions in 67 sets: literary narrative, social science, humanities and natural science, some with paired passages.
Timed sections
English: 50 questions in 35 minutes. Reading: 36 in 40. 4 of each come from a reserved pool that practice never shows.
Stats and an estimate
Accuracy by ACT's reporting categories, and the rules you miss most. Timed sections give an estimated score range on the 1 to 36 scale, labelled: estimated from your accuracy; not an official ACT score.
A study plan
Set your test date and 30, 45 or 60 minutes a day. A daily reminder is optional.
Offline and in sync
Planned for the web, Windows, iPhone and Android. Content stays on the device, and signing in syncs progress.
What your student does each day
15 new words, 2 rule cards, an English passage and a Reading set, 6 days a week. They choose 30, 45 or 60 minutes.
Progress they can show you
A Stats screen with answers, the share right in each ACT category and the rules missed most. A weekly progress email for parents is planned, not built yet.
No ads, no tracking, no data sold
This page has no analytics, ads or third-party scripts. The app has no ads. The phone apps send crash reports with no name or email, which can be turned off.
One payment, not a subscription
Planned: $39 for 3 months, from the day the code is activated. Extra time is optional.
How buying works
When it opens, you pay on this site and the receipt comes to you. Your student activates the code in their own account. The store apps sell nothing.
Age
For students aged 13 and over. A parent or guardian can set it up for a younger student.
What it leaves out
English and Reading only: no Math or Science. The composite score averages English, Math and Reading, so your student needs another source for Math.
No score promises
We promise no score. The range shown after a timed section is labelled as an estimate, not an official ACT score.
Fix the underlined part
On the test: 50 questions in 35 minutes, 10 of them unscored. Each one asks for the best version of a numbered, underlined part, or asks about the writer's choices.
- Every question is tied to one of the 124 rules
- The three areas ACT reports: Conventions of Standard English, Production of Writing and Knowledge of Language
- Every wrong choice has a note saying why it fails
When water carrying dissolved limestone drips from a cave's ceiling, it releases some of its carbon dioxide into the air. However, the water can no longer hold all of its dissolved mineral, and it leaves behind a tiny ring of calcite. Each of the many drops that follow adds another ring, and the rings slowly build a thin, hollow tube. Eventually, the tube's center becomes blocked, so water flows down the outside, and the tube thickens into the cone of a stalactite.
Question 3: choose the best version.
Show the answer
As a result. Losing carbon dioxide is what makes the water unable to hold all of its dissolved mineral, so the second sentence describes an effect of the first. As a result signals that cause and effect.
Read, then answer
On the test: 36 questions in 40 minutes, 9 of them unscored, across literary narrative, social science, humanities and natural science, including paired passages.
- All four genres, with paired passages
- The three areas ACT reports: Key Ideas and Details, Craft and Structure, and Integration of Knowledge and Ideas
- Every wrong choice has a note saying why it fails
An ice cube dropped into a glass of water bobs to the surface. The sight is so familiar that few people stop to wonder about it, yet ice breaks a common pattern. When most liquids freeze, their particles pack more tightly, so the solid sinks in its own liquid. That rule is valid for the great majority of substances: solid wax sinks in melted wax, and solid iron sinks in molten iron. Water is one of only a few exceptions.
First paragraph of 8.
The main purpose of the passage is to:
Show the answer
explain why ice floats on water and describe some effects of this unusual property. The second and third paragraphs explain the molecular reason ice floats, and the fourth through seventh paragraphs describe its effects on lakes, rocks, pipes, and the ocean. The passage as a whole explains the property and what follows from it.

Who writes the questions?
We write our own questions. A separate reviewer checks the facts and the key, and a separate solver answers each question without seeing the key. A question that fails goes back to be fixed. ACT has no part in them. Nothing is copied from ACT tests or prep books.
