The journey to college is filled with decisions, but one of the first major hurdles is choosing between the SAT and the ACT. For decades, students have weighed the pros and cons of each test. Now, with the SAT’s complete transition to a new digital format, that decision has become even more nuanced.
If you’re a student or parent staring at this crossroads, don’t worry. This guide will break down the essential differences between the Digital SAT and the ACT in 2025 to help you make a smart, informed choice.
The Big Picture: What’s the Same?
Before we dive into the differences, let’s cover the similarities. Both the SAT and the ACT are:
- Widely Accepted: Virtually all U.S. colleges and universities accept scores from either test with no preference.
- Core Subjects: Both test your skills in core academic areas: Reading, Writing (called English on the ACT), and Math.
- No Wrong-Answer Penalty: You are no longer penalized for guessing, so it’s always in your best interest to answer every question.
Key Differences: A Section-by-Section Breakdown
The real decision comes down to format, pacing, and content. Here’s how the two tests stack up.
1. Format and Timing
- Digital SAT: As of 2024, the SAT is now a fully digital, adaptive test. This means the difficulty of your second module of questions is determined by your performance on the first. The entire test is significantly shorter, clocking in at around 2 hours and 14 minutes.
- ACT: The ACT remains a traditional paper-and-pencil test for most students in the U.S. It is a static test, meaning everyone gets the same questions in the same order. It’s also longer, taking about 2 hours and 55 minutes (without the optional essay).
2. Reading Section
- Digital SAT: The Reading section is combined with the Writing section. It features numerous very short passages, with only one question tied to each passage. This tests your ability to analyze, synthesize, and use evidence on a micro-level.
- ACT: The Reading section consists of four long passages with 10 questions per passage. This format tests your ability to read quickly, locate information, and maintain focus over a sustained period.
3. Writing / English Section
- Digital SAT (Writing & Language): Integrated into the “Reading and Writing” section, these questions test grammar, punctuation, and rhetorical skills within the context of the short passages.
- ACT (English): This is a standalone section that is more direct in its testing of grammar, sentence structure, and punctuation. It often feels more like a pure editing test.
4. Math Section
- Digital SAT: The new digital format allows a calculator on the entire math section. The questions focus heavily on data analysis, algebra, and advanced problem-solving. A math reference sheet with common formulas is provided on-screen.
- ACT: You can use a calculator on the entire math section. The content is broader, covering a wider range of topics including arithmetic, algebra, geometry, and trigonometry. No formula sheet is provided, so you’ll need to have key formulas memorized.
5. The Science Section: The ACT’s Big Differentiator
- ACT: The ACT has a dedicated Science section. This is not a test of scientific knowledge. Instead, it measures your ability to interpret data, read graphs and charts, and understand scientific reasoning and experimental design.
- Digital SAT: The SAT does not have a separate Science section. It incorporates some data and graph interpretation questions throughout its Math and Reading/Writing sections.
At-a-Glance Comparison
So, How Do You Choose?
The best test for you depends entirely on your personal strengths and test-taking style.
- You might prefer the Digital SAT if: You are a strong analytical reader who does better with short-form content. You prefer having more time per question and excel at in-depth math problem-solving.
- You might prefer the ACT if: You are a fast reader and can process information quickly under pressure. You have strong time management skills and are comfortable interpreting charts and graphs, which will give you an edge on the Science section.
The Golden Rule: Take a Practice Test! The single best way to decide is to take a full-length, timed practice test for both the Digital SAT and the ACT. See how you feel during each test and, most importantly, compare your scores. Your performance will give you the clearest answer.
