UPSC Mains Syllabus  The UPSC Mains syllabus can also be called the Phase 2 syllabus. This is because only the candidates that are able to successfully clear the Phase 1 or the UPSC Prelims, are allowed to appear for the Phase 2 or UPSC Mains exam. Moreover, the UPSC Mains exam consists of 9 subjective type papers out of which 2 are qualifying language papers, one English, and any other Indian language of 300 marks each. The rest of the 7 papers have a maximum mark of 250. Also, it should be noted that not qualifying in the 2 language papers will cause the rest of your 7 papers to be disbarred from further evaluation. The minimum qualifying mark in the language papers is 25%. The UPSC Mains exam, fundamentally, is designed to test your understanding on the various subjects falling under the purview of the UPSC Mains syllabus, and it is designed to make you do so in a time-bound fashion. An important thing to note is that all the papers except for the 2 language papers included in the UPSC Mains syllabus can be written in any of the languages mentioned in Schedule 8 of the Indian Constitution.
