This is in the interest of all UPSC aspirants with Eng. Litt. as optional subject. The ones undecided about optionals and having Litt. as a probable choice can also benefit by knowing the question types asked and the answers expected. This is especially helpful for those without a literature background.
Sure, the answers posted here may not always be perfect (as this is a platform to help one start writing answers and sharpen your skills over time), but with the collective effort of members and guidance by senior players in the subject (mains qualified candidates) I think we can reach quite close to what UPSC expects of us.
To maintain quality of questions, it is recommended to attempt and post answers to only previous year UPSC questions.
