For decades, students applying to American colleges have faced the same question: SAT or ACT? Both tests are widely accepted, and most colleges have no preference. That means your goal is not to guess which test is “better” but to figure out which one lets you show your strengths. This guide compares the two exams, explains how to choose, and offers a study approach that respects your time. It also covers test-optional policies, which have changed how many students approach testing.
Test formats, scoring, and college policies change. Always confirm current details on the College Board and ACT websites and on each college’s admissions page.
The basics
The SAT is administered by the College Board, and the ACT by ACT, Inc. Both measure skills in reading, writing, and math, and the ACT also offers an optional science section in its current format. Colleges use scores as one factor alongside grades, course rigor, essays, activities, recommendations, and other materials. Many scholarships and state programs also use test scores for eligibility.
Test-optional and test-required policies
In recent years, many colleges adopted test-optional policies, which let you decide whether to submit scores. Some selective institutions have since reinstated testing requirements, while many others remain optional. Policies vary by school and can change from one admissions cycle to the next, so check each college on your list. Even at test-optional schools, a strong score can strengthen your application, especially if your grades are less impressive or your school is less well known. A score can also affect merit scholarship and honors program eligibility.
How the SAT works
The SAT is now delivered digitally at test centers in the United States. Key features include:
- Sections. Reading and Writing, and Math. Each is divided into two modules.
- Adaptive design. The second module in each section adjusts in difficulty based on how you did in the first.
- Shorter length. The digital SAT takes about two hours, shorter than the former paper test.
- Scoring. Total scores range from 400 to 1600, with section scores from 200 to 800.
- Reading style. Passages are shorter, each followed by one question.
- Calculator. A built-in graphing calculator is available for the entire Math section, and you can bring your own approved device.
How the ACT works
The ACT is also available in digital formats at test centers in some places, with paper testing still offered in others. Check the current options when registering. Key features include:
- Sections. English, Math, and Reading are required, and Science is optional in the current version.
- Scoring. Each section is scored from 1 to 36, and the composite score is an average of the required sections, also on a 1 to 36 scale.
- Pacing. The ACT has historically been known for tighter time per question, so pace matters.
- Reading style. Longer passages across multiple subject areas.
- Math. Covers algebra, geometry, and some trigonometry.
Because formats have been evolving, make sure any practice materials you use match the version you plan to take.
Key differences at a glance
| Feature | SAT | ACT |
|---|---|---|
| Score range | 400 to 1600 | 1 to 36 composite |
| Required sections | Reading and Writing, Math | English, Math, Reading |
| Science | No separate section | Optional section |
| Reading passages | Short, one question each | Longer passages with several questions |
| Pacing | More time per question on average | Faster pace |
| Calculator | Built-in graphing calculator | Calculator allowed on math section |
How to decide
Take a full-length practice test of each
This is the single best method. Both organizations offer free official practice tests. Take each under realistic conditions: timed, quiet, and without distractions. Compare your results using concordance tables, which convert scores between the two tests, and note which one felt more comfortable.
Consider your testing style
- Do you work best at a steady pace or under time pressure? If you tend to rush or run out of time, the SAT’s pacing may suit you. If you are fast and decisive, the ACT could work well.
- Are you comfortable with long reading passages? The ACT includes longer passages. The SAT’s shorter passages may be less taxing for some.
- Do you like adaptive tests? The SAT adjusts to your performance, which some students find less stressful and others find more unpredictable.
- How is your math? Both cover algebra and advanced topics. The SAT has a stronger focus on algebra and data analysis, while the ACT includes more geometry and trigonometry questions in the mix.
Think about your target colleges
Check whether your colleges require, recommend, or consider tests, and whether they accept both. A few state systems or scholarship programs may have specific policies. Also check whether they superscore, meaning they take your best section scores across test dates. Many do, which can affect how many times you test.
Weigh availability and logistics
Look at test dates, registration deadlines, test center locations, and fees. Fee waivers are available for eligible students, and some school districts offer free testing during the school day. Ask your school counselor.
Timeline for taking the test
Many students take their first official test in the spring of junior year, leaving time to retake in summer or fall if they want to improve. Some begin earlier or take a practice test in sophomore year to explore. A reasonable plan:
- Sophomore year or early junior year: take a practice test and learn what the test covers.
- Winter to spring of junior year: study for 8 to 12 weeks and take the first official test.
- Summer or early senior year: retake if your score is below your goal and the target colleges consider scores.
- Check deadlines: make sure scores arrive before application deadlines, including early action or early decision.
Most students gain from a second attempt, but returns tend to diminish after two or three tries.
How to prepare effectively
Use official materials first
The College Board offers free practice on its own platform, including partnerships with Khan Academy for the SAT. ACT provides free practice resources and official guides. Official materials most accurately reflect the real exam.
Diagnose weaknesses
After each practice test, review every missed question, not just the wrong answers but also the lucky guesses. Categorize mistakes: content gaps, careless errors, timing, or misreading. Target the biggest categories first.
Practice regularly
Short, consistent sessions of 30 to 60 minutes several times a week beat a single long cram. Include timed sections to build pacing.
Strengthen the underlying skills
Reading widely improves comprehension, and regular math practice supports problem solving. Writing and grammar rules can be learned, since both tests assess conventions such as punctuation and sentence structure.
Learn test-day strategies
- Answer easier questions first and mark harder ones for review.
- Do not leave answers blank when there is no guessing penalty, which is true for both tests.
- Use elimination to improve your odds on tough questions.
- Pay attention to what the question is actually asking.
Consider paid help carefully
Tutors and courses can help some students, especially those who benefit from accountability. They are not necessary. Free official resources are enough for many students, and expensive programs do not guarantee higher scores.
Test accommodations
Students with documented disabilities may qualify for accommodations such as extended time. Requests need to be submitted in advance through your school, so start early and talk to your counselor.
Managing stress
Test day can be nerve-racking. Get a good night’s sleep, eat breakfast, bring your ID and approved supplies, and arrive early. Remember that one score does not define you. Admissions officers look at your whole record.
Frequently Asked Questions
Do colleges prefer the SAT or the ACT?
Generally, no. Colleges accept both and treat them equally. Choose the one on which you perform better.
Should I take both tests?
Not necessarily. Most students do better by focusing on one test. If your practice scores are similar, pick the one you find more comfortable.
How many times should I take the test?
Many students test two or three times. Check whether your colleges superscore and how scores are reported.
Is it worth submitting scores to a test-optional college?
If your score is at or above the school’s typical range, it can help. If it is well below, you may leave it out. Check each college’s guidance.
Can I get fee waivers?
Yes. Eligible students can receive fee waivers for registration, and some also receive waivers for college application fees. Ask your counselor.
The bottom line
The best test is the one that reflects your strengths. Take a practice test of each, compare results and comfort, check your colleges’ policies, and then commit to a steady preparation plan. With a focused approach, you can show colleges what you can do without losing your whole school year to testing.
