A "Test Online Course" refers to an educational program available over the internet, designed to help students or professionals prepare for specific exams or assessments. These courses typically offer instructional videos, practice tests, quizzes, study materials, and sometimes live sessions with instructors. The goal is to improve learners' knowledge and skills in a focused area, such as standardized tests (e.g., SAT, GRE), certification exams (e.g., IT certifications), or professional qualification tests. Test online courses provide flexibility in terms of time and location, making it convenient for learners to study at their own pace.
