If you are planning to study abroad and are confused about which test you need to get admitted to top universities, then you have probably run into a wall of acronyms: SAT, ACT, GRE, GMAT.
In this blog, you will get all the necessary information you need to know upfront these tests because high schools and universities around the world grade students differently. Universities use these standardised tests as a universal ruler to compare fairly.
While many universities have gone “test-optional” recently (meaning you can apply without a SAT, ACT, GRE, GMAT score), although having a great score in any of these still gives you a massive advantage for getting accepted and more importantly landing scholarships and rewards. Thus, to learn more keep reading the blog!
SAT (Scholastic Assessment Test)
The SAT is the most widely recognised optional undergraduate admission test in the world. Owned and managed by the College Board, it is designed to measure a high school student’s readiness for college-level academics.
- Format: 100% Digital. The exam uses a multistage adaptive design, which means your performance on the first module determines the difficulty of your second module.
- Structure:
Reading and Writing: Short passages testing vocabulary, reading comprehension, and grammar.
Math: Covering algebra, advanced math, problem-solving, data analysis, geometry, and trigonometry. (Calculators are permitted for the entire math section). - Exam Duration: 2 hours and 14 minutes.
- Scoring: 400 to 1600.
- Fees: $68 base fee + $43 regional international fee (Approx. $111 total for international test-takers).
- Conducted by: College Board.
ACT (American College Testing)
The ACT is the primary alternative to the SAT. US universities treat both exams equally, but they differ in format and speed. The ACT is faster-paced but features slightly more straightforward questions.
- Format: Computer-based for international students.
- Structure: English, Mathematics, Reading, Science (which measures your ability to interpret charts, data, and scientific hypotheses), and an optional Writing section.
- Exam Duration: 2 hours and 55 minutes (plus 40 minutes if you take the optional essay).
- Scoring: 1 to 36 (average of the four core sections).
- Fees: Approximately $186.50 base international test fee (up to $221.50 depending on the optional Science and Writing add-ons).
- Conducted by: ACT, Inc.
GRE (Graduate Record Examinations)
If you are aiming for graduate school, the GRE is the absolute standard. It is accepted by thousands of graduate and business schools globally for Master’s, PhD, and MBA programmes.
- Format: Shorter, user-friendly digital test.
- Structure:
- Analytical Writing: 1 “Analyse an Issue” essay task.
- Verbal Reasoning: Sentence equivalence, text completion, and reading comprehension.
- Quantitative Reasoning: Basic arithmetic, algebra, geometry, and data analysis.
- Exam Duration: 1 hour and 41 minutes.
- Scoring: 130 to 170 each for Verbal and Quantitative sections (Total score scale: 260 to 340); Analytical Writing is scored from 0 to 6.
- Fees: Updated price bracket is ranged from $220 to $249 globally, according to 2026 latest update.
- Conducted by: Educational Testing Service (ETS)
GMAT (Graduate Management Admission Test)
The GMAT Focus Edition is built specifically for business schools. If your dream is a competitive MBA or Master’s in Finance, this is the exam that admissions committees prioritise.
- Format: Computer-adaptive by question. This means the test gets harder or easier with every single question you answer. You can review and change up to three answers per section.
- Structure:
- Quantitative Reasoning: Focuses strictly on arithmetic and algebra (no geometry, and calculators are not allowed).
- Verbal Reasoning: Critical reasoning and reading comprehension (sentence correction has been removed).
- Data Insights: Tests data literacy, chart analysis, and multi-source reasoning with an on-screen calculator.
- Exam Duration: 2 hours and 15 minutes.
- Scoring: 205 to 805. Each section is scored on a scale of 60 to 90.
- Fees: $275 at an official test centre or $300 for the online proctored version.
- Conducted by: Graduate Management Admission Council (GMAC).
Note: The previous “Classic GMAT” used a 200–800 scale. Universities compare scores using percentiles to ensure fair comparisons between the classic and focus editions.

Which Exam Do You Actually Need?
Before spending months studying and dollars on registration fees, it is important to know if an exam is a hard requirement or simply a strategic choice. So, use the following checklist to discover where you fit in:
SAT
The Target: You are a high school student or recent 12th-grade graduate aiming for a Bachelor’s degree in the US, Canada, or certain competitive global universities (like Bocconi in Italy or top schools in Singapore).
Is it Mandatory? It depends on the tier. A dominant majority of top-tier US universities (including Harvard, Yale, MIT, Stanford, Brown, and UPenn) have completely ended the “test-optional” policy and made the SAT mandatory. Mid-tier universities frequently remain test-optional.
The Exam Style: It is a fully digital, adaptive test taken on a laptop or tablet. The reading passages are very short (just one paragraph per question), and it gives you significantly more time per question compared to the ACT.
Why take it if it’s optional?
Financial Aid: It is the fastest trigger for automatic, merit-based international scholarships ($10,000 to $40,000+ per year).
Math Strengths: It is ideal for students who excel in Algebra and want to use an on-screen graphing calculator for the entire math section.
ACT
The Target: The exact same demographic as the SAT – high schoolers aiming for global undergraduate programmes. Every university that accepts the SAT will accept the ACT interchangeably with zero preference.
Is it Mandatory? Yes, at the same elite schools. If a school mandates the SAT, they will seamlessly accept the ACT as your mandatory submission instead.
The Exam Style: It is a traditional, linear test (the difficulty doesn’t change as you go). It is an intense, high-speed race with very tight time limits. Unlike the SAT, it includes long, full-page reading passages and features a dedicated Science section that tests your ability to interpret charts and graphs quickly.
Why take it if it’s optional?
Profile Booster: If your high school GPA is slightly lower, a stellar ACT score proves your academic readiness to admissions officers.
Fast Readers & Science Minds: It is the perfect strategic choice for students who naturally read and process information incredibly fast and prefer standard Geometry/Trigonometry over deep, conceptual algebra.
GRE
The Target: You already have a college degree and want to study a Master’s (MS) or PhD in fields like Engineering, Sciences, Humanities, or certain non-traditional Business programmes.
Is it Mandatory? No, it is rarely mandatory across the board anymore. Most graduate programmes have shifted to a test-optional model.
Why take it if it’s optional?
Funding & Assistantships: This is the big one. When departments distribute highly competitive Teaching Assistantships (TAs) or Research Assistantships (RAs), they use GRE scores as a baseline filter to break ties between applicants with identical GPAs.
Weighing Competition: For elite STEM programmes, a perfect or near-perfect GRE Quantitative score is a massive advantage that sets you apart from thousands of international applicants.
GMAT
The Target: You want to go to business school for an MBA or a specialised Master’s in Finance or Management.
Is it Mandatory? It depends on the tier. Top-10 global business schools strongly prefer or mandate the GMAT (or GRE Business track). Mid-tier schools frequently offer “GMAT waivers” if you have several years of solid professional work experience.
Why take it if it’s optional?
Corporate Recruitment: Elite consulting firms (like McKinsey or BCG) and top investment banks often ask for your GMAT score during job interviews after you start your MBA.
Demonstrating Quantitative Skills: If your undergraduate degree was in the Arts or Humanities, a strong GMAT score proves to a business school that you can handle rigorous financial and statistical coursework.
Is it Possible to Study Abroad Without Them?
Yes, it is absolutely possible to study abroad without SAT, ACT, GRE, GMAT. Standardised tests are a major boost, but they are not always mandatory.
The “Test-Optional” Era: Thousands of universities in the US, UK, and Europe do not strictly require SAT, ACT, GRE, or GMAT. Your profile is evaluated holistically, meaning they look at your GPA, Letters of Recommendation (LORs), Statement of Purpose (SOP), and extracurriculars instead.
Country-Specific Paths: Some universities of countries like – Canada, Australia, and the UK traditionally place much more focus on your high school or undergraduate GPA rather than standardised test scores.
Benefit of these Test
If universities are “test-optional,” why do people still stress over these exams? The answer is simple: A high standardised test score is one of the fastest ways to lower your tuition bill or secure fully funded positions.
Here is how a great score impacts your wallet and application value across the world.
1. The Undergraduate Level: SAT & ACT
At the Bachelor’s level, a high test score acts as an automatic trigger for Merit-Based Scholarships.
How it Works: Many public and mid-tier private universities (especially in the US) have specific score cutoffs. If you hit a certain score and have a decent GPA, you are automatically awarded a scholarship – no extra application required.
The Cash Value: This can range from $10,000 to $40,000 per year. For international students, a high SAT score often covers the massive gap between “in-state” and “out-of-state” tuition fees.
Worldwide Impact: In countries like Italy (e.g., Bocconi University) or Singapore, a top-tier SAT score is heavily weighted when handed out to international students looking for full tuition waivers.
2. The Postgraduate Level: GRE & GMAT
At the Master’s and PhD levels, funding changes from “scholarships” to Graduate Assistantships.
How it Works: You are hired by the university as a Teaching Assistant (TA) or Research Assistant (RA). You help grade papers, run labs, or work on research projects.
The Cash Value: This is the ultimate jackpot for study abroad. An assistantship usually provides a 100% tuition waiver plus a monthly stipend (around $1,500 to $3,500/month) to cover your rent and food.
The Test Connection: While a professor looks at your background, the university graduate school often uses GRE/GMAT scores as a baseline filter to allocate university-wide fellowships and competitive funding pots. If two students have a 3.8 GPA, the one with a 167 GRE Quant score will almost always secure the funding.
How Universities View Multiple Attempts
A major relief for students is that you rarely have to rely on just one testing session. Most top universities understand that people have bad days, so they utilise evaluation systems called Superscoring and Score Choice.
Superscoring (Common for SAT & ACT): This is where a university takes your highest section scores across different test dates to create your ultimate best score. For example, if your Math score was better in October but your Reading score was better in December, the school blends them together.
Score Choice (Common for GRE & GMAT): Programmes like ETS’s ScoreSelect or GMAC’s digital platform allow you to choose exactly which test day scores are sent to universities. If you took the GRE three times and messed up the second attempt, your target universities will never see it they only see the specific test date score report you pay to send them.
Retake Rules & Strategic Timelines: Making Every Attempt Count
Because preparation takes time and registration costs are high, you need to budget your attempts carefully. Testing agencies enforce mandatory waiting periods between retakes that can clash with tight university admission deadlines:
SAT/ACT Limits: There are no strict waiting periods between consecutive test dates, but exams are only held on fixed weekends roughly 7 times a year. You should aim to take your first attempt at least 6 months before your deadlines to allow proper breathing room for a second try.
GRE Retake Rules: You can take the computer-delivered GRE once every 21 days, up to 5 times within any continuous rolling 12-month period.
GMAT Focus Retake Rules: You must wait a minimum of 16 days between attempts. You are limited to a maximum of 5 attempts within a single year and an absolute lifetime limit of 8 attempts.
