1. Pick classes wisely: Take your English proficiency and cultural experience into account when choosing courses. If you are a freshman who started learning English a year ago, taking a high-level reading- and writing-based humanities class, such as History of Philosophy, might not be a good idea. Most colleges have course prerequisites and many have a ranking system to help students understand the difficulty level of each course. As an international student, you should pay attention to this information, as well as the level of English proficiency that is required for each class. Save classes that require a strong vocabulary for later years. When you start college, it is best to take entry-level classes that fulfill the general interdisciplinary requirements. For example, your first class could be calculus, which would satisfy a mathematics requirement and doesn't require the level of English proficiency a political science course would.
Don't let this stop you from pursuing your interests. If you want to major in Comparative Literature, you should definitely take classes in the English department. However, it might be best to start with a class on short stories your freshman year and wait until you're a senior to take literary theory or dive into a course that requires you to read "War and Peace." Throughout your time at school, your English will naturally progress. Trying to take classes that require a sophisticated understanding of the English language too early might not only make it harder for you to earn good grades, but could suppress your interest in a certain subject.
2. Get help if you're struggling: Most college professors are very understanding about the challenges that international students face in the classroom, and will try to help you as much as possible if they are aware of your problems. When I took American history in college, I had a very difficult time because I didn't have the high school history knowledge that my American classmates did. When I expressed concern to my professor, he gave me a few books that had a lot of background information and found me a tutor within the department. Many colleges also have a writing center whose staff will help you edit your papers. These centers frequently have reference books and sample essays, and are excellent resources for international students.
3. Take English as a Second Language classes: Many colleges offer supplementary ESL courses, which I think are a great way to improve your English and lower the language barrier. A friend of mine took an ESL course throughout her freshman year, and by her sophomore year, was ready to sign up for high-level humanities courses. Many college ESL teachers make it their goal to improve your class participation and extend your vocabulary. Spending a small portion of your week taking those classes can be very beneficial for your college career.
3. 将英语作为第二语言课程修读：许多学校提供辅助的ESL(ESL - English as a Second Language，母语非英语)课程，我认为这是个提高英语水平很好的方式，从而也减少了语言障碍。我的一个朋友就在大一的时候修读了一门ESL课程，当她大二的时候，已经有能力报名修读高级人文课程了。许多学校的ESL教师都把提高你的课程参与性和增加词汇量作为他们的目标。用你一周中占很小一部分的时间修读这些课程可能会使你的大学时光受益匪浅。
4. Study hard and be patient: A challenging class can be a great source of stress and frustration, but remember that hard work pays off. You may have to spend more time studying than other students because there are words that you don't know, or because you can't read as quickly in English, but it could also mean that you will remember information longer than your classmates will. Also, when you find class difficult, other students probably do as well. Be patient and kind to yourself and your efforts will be recognized.
