ProfessionalWhen people talk about competitive exams in the USA are standardized tests used for college admissions, graduate school entry, and professional licensing, they usually mean a handful of wellâknown assessments. Whether youâre aiming for an undergraduate slot, a masterâs degree, a medical license, or a legal career, knowing which exam fits your goal is the first step.
competitive exams USA cover a wide range of subjects, formats, and stakes. Below youâll find a clear map of the most common tests, why they matter, and practical tips to ace them.
Key Takeaways
- College admissions rely mainly on the SAT or ACT; choose based on your strengths.
- Graduate school candidates need the GRE, GMAT, or LSAT depending on the program.
- Professional licensing exams such as the MCAT, USMLE, and NCLEX have strict content outlines and early registration deadlines.
- Preparation strategies are similar across exams: understand the format, practice with official materials, and schedule realistic study milestones.
- Use free resources from test makers (College Board, ETS, NBME) before investing in paid courses.
Major Categories of Competitive Exams
Think of the landscape as three groups: undergraduate admissions, graduate admissions, and professional licensing. Each group has its own set of flagship exams.
Undergraduate Admissions
SAT is a collegeâentrance exam administered by the College Board, testing reading, writing and math. The test lasts three hours and scores range from 400 to 1600.
ACT is a rival exam created by ACT, Inc., covering English, math, reading, and science, with an optional writing section. It takes about three hours and scores range from 1 to 36.
Both exams are accepted by virtually every U.S. college. Some schools also consider PSAT/NMSQT as a practice test and a qualifier for National Merit scholarships. Advanced Placement (AP) exams and the College Level Examination Program (CLEP) let students earn college credit while still in high school.
Graduate Admissions
GRE is the Graduate Record Examination offered by ETS, measuring verbal reasoning, quantitative reasoning, and analytical writing. Most masterâs and PhD programs require it.
GMAT is a businessâschool entrance test focusing on analytical writing, integrated reasoning, quantitative, and verbal skills. Top MBA programs look closely at the GMAT score.
LSAT is the Law School Admission Test, evaluating reading comprehension, analytical reasoning, and logical reasoning. Law schools use it as a primary admissions metric.
Professional Licensing
MCAT is the Medical College Admission Test, covering biological and physical sciences, verbal reasoning, and writing. It is required for all U.S. medical schools.
USMLE is the United States Medical Licensing Examination, a threeâstep series that physicians must pass to practice medicine. Step1 focuses on basic sciences, Step2 on clinical knowledge and skills, and Step3 on independent practice.
Other notable licensing exams include the NCLEX for nursing, the CPA exam for accounting, and the Bar Exam for lawyers.

Choosing the Right Exam for Your Goal
- Define your target. Are you applying to a fourâyear university, a graduate program, or a professional school?
- Check the requirements. Each school lists accepted exams on its admissions page. Some schools accept both SAT and ACT; many graduate programs prefer the GRE but allow the GMAT for business schools.
- Assess your strengths. SAT leans more toward math and evidenceâbased reading, while ACT adds a science reasoning component. GRE quantitative is tougher than the GMATâs, but the GMAT includes dataâsufficiency questions that many find tricky.
- Consider timing and cost. Register early to secure a test date, and factor in registration fees (e.g., SAT â $55, GRE â $220). Some tests offer fee waivers for lowâincome applicants.
- Plan for retakes. Most exams allow multiple attempts; know the policies for score superseding and how schools view multiple scores.
Effective Preparation Strategies
Preparation looks similar across exams, but each has unique quirks.
- Start with the official guide. The College Boardâs Official SAT Study Guide, ACTâs Official Guide, ETSâs GRE PowerPrep, and NBMEâs USMLE practice exams provide the most accurate question style.
- Diagnose your baseline. Take a timed practice test to identify weak areas before you build a study schedule.
- Set a realistic timeline. For most students, 8â12 weeks of focused study yields a 100âpoint jump on the SAT or a 4âpoint rise on the ACT.
- Mix free and paid resources. Khan Academy partners with the College Board for SAT math videos; Magoosh and Manhattan Prep offer affordable GRE/GMAT question banks.
- Practice under test conditions. Simulate the exact timing, breaks, and calculator policy to build stamina.
- Review mistakes. After each practice session, catalog every error, understand why it happened, and create a âmistake logâ to revisit weekly.
Comparing SAT and ACT at a Glance
Feature | SAT | ACT |

Administered by | College Board | ACT, Inc. |
Sections | Reading, Writing & Language, Math (NoâCalc & Calc), Optional Essay | English, Math, Reading, Science, Optional Writing |
Total time | 3 hours (plus 50âminute essay if taken) | 2 hours55 minutes (plus 40âminute essay if taken) |
Scoring range | 400-1600 (essay scored separately) | 1-36 (composite; essay scored separately) |
Math focus | Algebra, geometry, some trigonometry, data analysis | Algebra, geometry, trigonometry, some calculus concepts |
Science component | None (integrated in reading passages) | Dedicated Science reasoning section |

Common Pitfalls to Avoid
- Skipping the official practice test because it feels âtoo hard.â Real test conditions are the best predictor of performance.
- Relying solely on flashcards for contentâheavy exams like the MCAT or USMLE. Those tests demand deep conceptual understanding, not rote memorization.
- Ignoring the essay component when you plan to apply to schools that require it. A weak essay can drag down an otherwise strong score.
- Procrastinating registration. Test centers fill quickly, especially in peak months (April-June for SAT/ACT, August-October for GRE/GMAT).
- Overâstudying the same material without varied practice. Mix timed quizzes, fullâlength tests, and targeted drills.
Next Steps and Resources
Now that you know the landscape, follow this short checklist:
- Mark the exam(s) required for your target program on a calendar.
- Register for the test date that gives you at least 10 weeks of prep time.
- Download the official study guide and take a diagnostic test.
- Create a weekly study plan with specific goals (e.g., âBoost SAT math percentile by 10% in 4 weeksâ).
- Schedule one fullâlength practice test per month, reviewing mistakes each time.
- Consider a shortâterm prep course if you need structure, but start with free resources first.
Good luck, and remember that consistency beats cramming every time.
Frequently Asked Questions
Do I need to take both the SAT and ACT?
No. Most colleges accept either score. Choose the test that matches your strengths or the one you can schedule more conveniently.
Whatâs the best time to start studying for the GRE?
Ideally 3-4 months before your intended test date. This gives you enough time for content review, practice, and multiple fullâlength tests.
Can I use the same study materials for the GMAT and GRE?
Some resources overlap in quantitative sections, but the GMATâs Integrated Reasoning and Data Sufficiency questions require separate practice.
How many times can I retake the USMLE?
You can take each Step up to six times, but many programs set their own limits, so plan carefully.
Is the MCAT harder than the SAT?
Hardness is relative. The MCAT covers collegeâlevel science and reasoning, while the SAT tests highâschool level skills. Most testâtakers find the MCAT more demanding because of depth and stamina required.
