To study abroad, particularly in countries like the USA, UK, Canada, or Australia, you'll typically need to take several standardized tests. For English proficiency, exams like the TOEFL (Test of English as a Foreign Language) or IELTS (International English Language Testing System) are commonly required. For undergraduate programs, the SAT (Scholastic Assessment Test) or ACT (American College Testing) are often necessary. For graduate programs, the GRE (Graduate Record Examination) is widely accepted, while business schools usually require the GMAT (Graduate Management Admission Test). Specific exams might vary based on your chosen field of study and destination country, so it's essential to check the exact requirements of the universities you're interested in. Additionally, each country may have its own set of requirements and standardized tests, so thorough research and preparation are key.
