I'm pursuing my Bachelor's degree without any specialization. Will I be able to do Master's in mass communication or travel and tourism?

You can pursue any course with a specialization once you pursue a Masters course.

Hi, Yes, you can pursue but for that you have to crack an entrance exam of it, and prepare it by Reading newspapers, watch news, practice reasoning, grammar and general knowledge. Either buy a book which covers all the above syllabus, or you can prepare from All India Exams online: http://www.allind
