The SAT and ACT are both widely accepted for undergraduate admissions abroad, but their suitability depends on individual strengths. The SAT emphasizes reasoning and problem-solving, with a stronger focus on math and evidence-based reading. The ACT includes a science section and tends to be more curriculum-based, covering English, math, reading, and science.
Consider your academic strengths: students excelling in science may prefer the ACT, while those strong in math might opt for the SAT. Check the requirements of your target universities, as some may prefer one test over the other. Preparation materials and practice tests can help determine which exam aligns better with your skills.
