Key takeaways
Choosing between the SAT and ACT involves understanding your strengths and the specific content of each test. Both exams are widely accepted by universities, but they differ significantly in structure and focus. Knowing these differences can help you select the test that aligns best with your skills and preparation strategy.
- The SAT score range is 400-1600, while the ACT ranges from 1-36 (College Board, ACT).
- The SAT emphasizes algebra and evidence-based reading, whereas the ACT includes a dedicated science section and covers a broader range of math topics.
- The ACT is increasingly accepting superscores, with more schools adopting this policy (2025).
- To prepare effectively, take practice tests for both exams to identify which format suits you better and focus on your weakest areas first.

Choosing between the SAT and ACT can feel like picking between Coke and Pepsi—but the differences are more than just branding. Here’s how to figure out which test fits your strengths and goals in 2025.
What’s the Real Difference Between ACT and SAT?
Here’s a side-by-side comparison to start:
| Feature | SAT | ACT |
| Total Score Range | 400-1600 | 1-36 |
| Parts of the Test | 2 sections (Reading & Writing, Math), 800 points each | 4 sections (English, Math, Reading, Science), each scored 1-36 |
| Essay | Discontinued | Discontinued (was optional) |
| Guessing Penalty | No penalty | No penalty |
| Score Averaging | Section scores added for total | Section scores averaged for composite |
Which Test Is Better for You: ACT or SAT?
Both tests are accepted equally by most universities, but they’re not the same. The key isn’t choosing the “easier” test—it’s choosing the one that plays to your strengths.
The SAT rewards strong algebra skills and evidence-based reading. The ACT covers more ground in math and includes a full science section. Some students perform better when they can take their time and dig deep. Others do best when they can move quickly and rely on instinct.
How the Test Content Compares?
Here’s a side-by-side snapshot of how the two tests compare:
| Section | SAT | ACT |
| Reading | Fewer questions, longer passages | Shorter passages, more direct questions |
| Writing/English | Pay attention to grammar and how ideas are organized | The content is similar, but there’s a bit more focus on grammar rules |
| Math | Divided into two modules (calculator and no calculator), fewer word problems | The math is simpler but covers more topics, like matrices |
| Science | No dedicated section—science reasoning is embedded in reading and data questions | The science part checks how you understand data and experiments |
| Essay | Removed in 2021 | |
What the ACT Science Section Is About?
The content covers biology, chemistry, physics, and Earth/space sciences, but the real skill it tests is scientific reasoning. Here’s a breakdown of the types of passages you’ll see:
| Group | What It Tests? | What It Looks Like? |
| Data Representation | Graph reading, pattern recognition | Charts, tables, graphs with trends |
| Research Summaries | Understanding experimental design | Two or more experiments with methods/results |
| Conflicting Viewpoints | Analyzing theories and disagreements | Two or more scientists or students with opposing explanations |
Most questions don’t require outside knowledge—but having basic familiarity with things like pH, gravity, or DNA helps you feel more confident. What matters most is your ability to process complex visuals quickly and make smart inferences.
The SAT doesn’t have a dedicated science section, but similar skills show up in cross-test score questions (data analysis in reading/math).
What’s New with the ACT?
Here’s a snapshot of what’s changing—and what’s not:
| Element | Version of 2024 | Version of 2025 |
| Test format | Mostly paper | Digital expanding in U.S., still paper-optional |
| Part timing | Same | Same (English: 45 min, Math: 60, Reading: 35, Science: 35) |
| Content updates | Minor | Subtle rebalancing in Reading and Science |
| Writing (Essay) | Officially discontinued in most schools | Fully phased out nationally |
| Superscore policy | Optional per college | More schools now accept ACT Superscores by default |
How to Prepare for Either the ACT or SAT?
Legacy Online School helps students build the confidence and skills they need to succeed on the SAT® and ACT®. If you’re serious about improving your score, we’re here to guide you every step of the way.
Regardless of the test, prep smart:
- Use official websites to see how the test works
- Use score calculators to track growth (e.g., UWorld, Bluebook)
- Focus on timing drills—most mistakes happen under pressure
- Choose a structured plan like those from Legacy Online School or Khan Academy (SAT)
- Target your weakest section first, then balance across all areas
“I got a 1560 and my biggest piece of advice is to take practice test after practice test. I didn’t sign up for a tutoring service or online program. Instead, I printed out loads of practice tests that I found online (from the past decade or so) and took each, went through all of the problems, understanding why I got certain questions right and why I got certain questions wrong. I then underlined and highlighted patterns that I noticed through the sections and made myself a ‘guide’ with tips and valuable content. I’d recommend this method, but, of course, everyone learns differently”
