Well they differ. Psychology is a science, but not considered with the same regard as the traditional sciences like chemistry. English Language is a traditional subject but you may be better taking English Literature if you want to do Law/Journalism. Media Studies is ok, but there are other subjects that carry more weight. Law depends upon the exam board.
But this is the important thing. Take subjects that you like and enjoy, not because of the status. Plus do not take my word to heart, I am not 100 percent.
