How the ACT is scored
The ACT reports a Composite score on a scale from 1 to 36. Each of the English, Mathematics and Reading sections earns its own score on that same 1 to 36 scale, and the Composite is the rounded average of those three.
Science is scored separately and does not count toward the Composite on the enhanced ACT, though many colleges still look at it. Every question offers 4 answer choices. Because a wrong answer costs nothing, only correct answers add to the raw score, so leaving a question blank never helps and a reasoned guess on every item is the sensible strategy.
What the paper is made of
| Section | Questions |
|---|---|
| English | 50 |
| Mathematics | 45 |
| Reading | 36 |
| Science | 40 |
What the app estimates
As you practice, the app keeps an estimate of your ability per section and maps it onto the Composite scale. It is the app's own estimate from your answers, not an official conversion table.
| Ability estimate | Composite |
|---|---|
| 250 | 13 |
| 350 | 14 |
| 450 | 17 |
| 550 | 21 |
| 650 | 25 |
| 750 | 29 |
Every question is picked for where you are right now, wrong answers come back until they stick, and it all works offline.
