+2 for a correct answer and −1 for a wrong one here; UPSC deducts a third of a question's marks, so a score on this page is a little stricter than the exam. The subject-wise papers are longer than the exam on purpose: one subject, every angle.
Each subject paper holds one GS Paper I subject so you can isolate a weak area instead of guessing where you lost marks on a mixed paper. The questions were drafted by an AI pipeline from the year’s priority current-affairs events and the static syllabus behind them, in the statement-based, match-the-pairs and "how many of the above" shapes UPSC uses.
Every question was then reviewed by a human before publication, and every question carries an option-by-option solution. The intent is to mirror the structure, difficulty spread and topic weight of GS Paper I, not to reproduce any past question.
The full GS mocks are cut from the same reviewed bank in the exam’s subject mix and shape, so a sitting feels like the paper: mixed subjects, the real duration, negative marking on.
When the Prelims paper came out in May, we hand-checked it by meaning against what this series had covered. The result is on the coverage analysis page, linked below; it is a by-topic match, not the same questions, and no one had the paper in advance.
