Contact the dean to obtain permission to take correspondence courses if you are part of a university or college program. Most institutions offer some form of correspondence courses or can accommodate students who want to take correspondence courses; however, you will need to obtain permission, and usually, a letter from the dean. Arrangements with the teacher must be made if the course is not typically a correspondence one.
Find a university that offers correspondence and distance education courses if your current university does not offer it. Duke University, the University of Florida and Indiana University, are examples of universities that offer English language correspondence studies. Aside from university, there are also other training facilities that offer the opportunity to learn English through correspondence, not just universities and colleges, such as Language Tutoring.
Be prepared. Look at the course list and order the text books and any other materials that you need for the course. Set aside time each day or every two days to make time for your studies. This means no multitasking. You have to dedicate yourself to the subject in order to succeed and this means the fewer distractions you have the better. Let your family know about your study schedule and ask them to keep distractions to a minimum when you are studying.
Follow the instructions and complete the activities as set out by the instructor. Some correspondence courses also have online forums for students to brainstorm or ask questions to the instructor or other students. Take full advantage of the resources that are made available to you during your course.
Take initiative. Learning English is not just about completing the assignments. Try to watch movies and listen to music in English to help immerse you into real-life situations that involve the English language. If you have any English-speaking friends, engage in English conversations with them. The idea is to use the language as much as you can to help you learn at a faster rate.
