Of course, British and American literature is the best. I chose it after listening to the guidance of the previous senior. If you don't have a high score on your thesis, write a document, because a good thesis depends on how many references you can choose. Generally, when you choose a topic, the teacher will give you a password of the library database, and you can search for references in the paper. Some of our students choose British and American culture, which looks easy to write, but there are few materials to quote, so translation is still necessary.
At that time, our requirements were extremely strict. I changed them six or seven times, but I always felt that the tutor I caught up with was a bit of a locomotive. In the literature I chose, I used 24 pages (including the catalogue, etc. ) to make a job. We also require theory when writing literary papers. I suggest you go to the library to find a book about British and American literary theory.
