When aiming to study in the United States, a standardized test is an exam that measures academic readiness and English proficiency, required by most U.S. colleges and universities becomes the first hurdle. With a dozen different exams floating around, it’s easy to feel overwhelmed. This guide cuts through the noise, helping you pick the best test for study in the USA based on your target program, timeline, and personal strengths.
Why a Test matters for U.S. Admissions
U.S. institutions use test scores as a common data point to compare applicants from diverse education systems. Scores help admissions committees gauge:
- Academic preparedness for college‑level work.
- Readiness for graduate‑level research or professional study.
- English language competence for non‑native speakers.
Because scores are standardized, they level the playing field when your high‑school grades or undergraduate GPA come from a curriculum that looks different from the U.S. one.
Key Exams to Know
Below are the most common exams you’ll encounter. Each section introduces the test with a brief definition and the typical profile of students who benefit most.
SAT is a college‑entrance exam focusing on reading, writing, and math, scored on a 400‑1600 scale. It’s widely accepted by U.S. undergraduate programs and is a good fit if you enjoy problem‑solving, have strong grammar skills, and prefer a single‑day test.
ACT is another college‑entrance exam that adds a science reasoning section, scored on a 1‑36 scale. It suits students who excel in quick‑thinking and like a broader subject mix.
GRE is a graduate‑record exam used by most U.S. master’s and PhD programs, covering verbal reasoning, quantitative reasoning, and analytical writing. It’s the go‑to for engineering, humanities, and social‑science master’s applicants.
GMAT is a business‑school exam that tests analytical writing, integrated reasoning, quantitative, and verbal skills, scored on a 200‑800 scale. Choose it if you’re eyeing an MBA.
TOEFL is an English‑proficiency test for non‑native speakers, scored out of 120, recognized by virtually all U.S. institutions. It’s computer‑based and favors academic English.
IELTS is another English‑proficiency test, scored on a 0‑9 band, popular with schools that accept a broader range of international credentials. It includes a speaking interview with a human examiner.
MCAT is the Medical College Admission Test, a 472‑point exam required for U.S. medical schools. If you’re aiming for a MD program, this is non‑negotiable.
LSAT is the Law School Admission Test, scored on a 120‑180 scale, essential for admission to U.S. JD programs. It emphasizes logical reasoning and reading comprehension.
How to Choose the Right Test
Pick the test that aligns with three core questions:
- What program am I applying to? Undergraduate? Graduate? Professional school?
- Which test does my target school accept? Most schools list required or optional tests on their admissions pages.
- What are my strengths? Math‑heavy vs. language‑heavy, timed‑section comfort, preference for computer‑based vs. paper‑based.
Answering these will narrow the list dramatically. For example, if you want a bachelor’s degree in engineering, the SAT or ACT is sufficient; a high SAT math score can offset a moderate reading score. If you’re applying for a master’s in computer science, the GRE’s quantitative section becomes the focal point.
Comparison Table: SAT, ACT, GRE, GMAT, TOEFL, IELTS
Test | Primary Use | Score Range | Typical Cost (USD) | When to Take | Best For |
---|---|---|---|---|---|
SAT | Undergraduate admission | 400‑1600 | $55 | Junior year or summer before senior year | Students strong in math, prefer single‑day test |
ACT | Undergraduate admission | 1‑36 | $63 | Junior year or summer before senior year | All‑rounders who like a science section |
GRE | Graduate admission (non‑business) | 260‑340 (Verbal+Quant), 0‑6 (Writing) | $205 | 6‑12 months before application deadline | Students pursuing master’s/PhD in STEM or humanities |
GMAT | Business school (MBA) | 200‑800 | $250 | 6‑12 months before application deadline | Aspirants to top‑ranked MBA programs |
TOEFL iBT | English proficiency for all programs | 0‑120 | $215 | When you need proof of English, usually 6‑12 months prior | Students comfortable with computer‑based testing |
IELTS Academic | English proficiency for all programs | 0‑9 band | $245 | Same timeline as TOEFL | Students who prefer a face‑to‑face speaking component |

Step‑by‑Step Checklist for Test Planning
Use this practical list to keep your timeline on track:
- Identify your target program(s) and note their specific test requirements.
- Pick the test that aligns with your strengths and the school’s preference.
- Register for the test at least 4‑6 weeks before your desired test date.
- Gather official study resources (College Board, ETS, official guidebooks).
- Create a weekly study schedule - 1‑2 hrs on weekdays, 3‑4 hrs on weekends.
- Take at least one full‑length practice test under timed conditions.
- Analyze mistakes, focus on weak areas, and retake practice tests.
- Schedule a test‑day rehearsal (travel route, ID requirements, snack).
- Take the exam, stay calm, and follow the time‑management plan you practiced.
- Send scores to your schools promptly; most platforms allow direct score reporting.
Following these steps reduces last‑minute panic and gives you a clear path from decision to score report.
Common Pitfalls and How to Avoid Them
- Choosing a test based on popularity alone. A school might weigh GRE scores heavily, while another accepts both GRE and GMAT - pick the one you can score higher on.
- Delaying registration. Test slots fill quickly, especially for peak dates (October, December, March). Register early.
- Relying solely on free online resources. Official practice tests mirror real exam difficulty; they’re worth the investment.
- Neglecting the English‑proficiency test. Some schools accept either TOEFL or IELTS; choose the one where you historically score better.
- Skipping the mock test on the actual test day format. Practice on a computer if you’ll take the digital SAT; this avoids surprise delays.
Pro Tips from Admissions Experts
Here are nuggets that often don’t appear in official prep books:
- Superscoring matters. Many U.S. schools combine your best section scores from multiple SAT or ACT attempts. If your math is great but reading is weaker, consider a second sitting.
- Take the TOEFL early. Scores are valid for two years; an early test gives you a buffer to retake if needed.
- Leverage free university‑hosted workshops. Many U.S. campuses run virtual SAT/ACT prep webinars for international students.
- Don’t ignore the writing sample. A well‑crafted essay can tip the balance in a tightly‑matched applicant pool.
- Use the “predictive score” tools. Official test makers (College Board, ETS) offer calculators that estimate how a target score translates to percentile ranks.

Next Steps After Getting Your Score
Scoring isn’t the finish line. Here’s what to do next:
- Compare your score against the average admitted range of your target schools.
- If you’re below the median, decide whether to retake or strengthen other parts of your application (e.g., GPA, extracurriculars, personal statement).
- Send official score reports via the test’s online portal; many schools accept electronic transmission.
- Upload unofficial scores to your online application to show early progress.
- Prepare additional documents (transcripts, recommendation letters) while awaiting score verification.
Staying organized after the test keeps momentum high and reduces stress during the application window.
Frequently Asked Questions
Do I need both the SAT and the ACT?
No. Most U.S. colleges accept either test. Choose the one that aligns with your strengths; you can also submit scores from both if you think one will boost your profile.
Can I skip the TOEFL if I have a high IELTS score?
Yes, most schools consider IELTS and TOEFL interchangeable. Verify the acceptable scores on each school’s website before deciding.
How many times should I take the GRE?
Most candidates take the GRE once or twice. If your first score is within the target range, a retake is rarely needed. If you’re far below, a second attempt after focused study can improve your percentile by 10‑20 points.
Is the GRE required for business school?
Many MBA programs prefer the GMAT, but a growing number accept the GRE as an alternative. Check each program’s policy; if you’re stronger in quantitative reasoning, the GMAT might give you an edge.
What’s the fastest way to improve my SAT math score?
Focus on high‑frequency topics: linear equations, geometry, and data analysis. Use official practice questions, time yourself, and review each mistake to spot patterns.
Quick Takeaways
- Undergraduate: SAT or ACT - choose based on your math vs. reading strengths.
