The IELTS exam is a standardized English language proficiency test designed for non-native speakers applying to study or work in English-speaking countries. It offers two modules: Academic for higher education and General for work or immigration, each with different focuses in writing and reading sections. Test results are scored on a 0-9 scale, with universities typically requiring a score of 6.5 or higher, and the exam includes sections on listening, reading, writing, and speaking.
