An IELTS 7.5 score is a good score, but it is not guaranteed to get you a scholarship from a good university. Many universities offer scholarships to international students, but they also consider other factors such as academic performance, work experience, and extracurricular activities.
If you are hoping to get a scholarship from a good university, it is important to have a strong overall application. This means having a good GPA, strong letters of recommendation, and a well-written personal statement. You should also consider applying for scholarships that are specifically designed for international students.
