To demonstrate English language proficiency when applying to universities abroad, you typically need to take standardized tests such as the TOEFL (Test of English as a Foreign Language) or the IELTS (International English Language Testing System). These exams assess your reading, writing, listening, and speaking skills. The required scores vary by institution, so it is essential to check the specific requirements of the universities you are applying to. Additionally, some universities accept other tests like the PTE Academic (Pearson Test of English) or Cambridge English exams. Preparing for these tests involves studying the format and content, practicing sample questions, and sometimes taking preparatory courses. Once you achieve the required score, you submit your results as part of your application to demonstrate your ability to succeed in an English-speaking academic environment. I would advise that you get in touch with a prominent abroad education advisor - a great one will really help you through the entire process, end-to-end. Hence, I would recommend you to focus on that first. Invicta Career Consultancy is one such company, which specializes in training, abroad education and all the related guidance.
