The best exam for studying abroad depends on your destination and program. For English-speaking countries, IELTS and TOEFL are widely accepted for language proficiency. The IELTS is preferred in the UK, Australia, and Canada, while TOEFL is common in the US.
For undergraduate programs, the SAT or ACT is required in the US, while the UK often asks for A-levels or IB scores. Graduate programs typically require GRE or GMAT, with GRE for most fields and GMAT for business schools. Always check the specific requirements of your chosen university and country to determine the best exam for your goals.
