What is the particular problem behind it? Getting the main point, structuring the answer, using the right words? These aspects should be addressed differently, but they seem to be clear and easy to improve on. Like, learn to quickly capture the core points of a book or film, train this ability by doing it after each movie orbook. Look at some good book/film reviews to learn how they are structured, what words are used. Train to write or talk aboun them the same exciting way.
