In recent years, those aspiring to the UPSC/CSE and prepping up for the IAS Mains Exam have made anthropology one of their preferred UPSC optional courses. Its popularity is due to the availability of materials for study combined with a syllabus that is simple to follow. Since anthropology involves parts of science, it is frequently chosen by science graduates. It is easier for science students to understand the theories, concepts, and guiding principles of anthropology. The study materials for anthropology are easily accessible online and in libraries.
Your first goal should be to establish conceptual clarification and knowledge of the subject if you are unfamiliar with it. With an emphasis on human nature, both biologially and culturally through the use of biology, archaeology, cultural studies, linguistics, and other sociology, anthropology involves the study of humankind, both present and past.
The end of the preliminary exams is the ideal time for preparing the subject. As far as you can, try answering questions that are based on theories and physical anthropology. Make a note of case studies and apply it where a concept needs to be explained. For the physical portion, try including diagrams because they can possibly fetch you more marks. Make detailed notes for concepts and theories.
