Where the questions come from
Current affairs questions are drawn mainly from The Hindu, The Indian Express and the Press Information Bureau. The rest can be traced to other well established newspapers and magazines, and to government websites: ministries, regulators and the official reports they publish. Every solution names the source it was built from.
Sourcing
Every static question is traceable to a defined source: NCERT, the standard reference for that subject, a government document, or an established Prelims pattern.
Alignment
Every sectional is set after the classes on that subject in Prelims from First Principles, and every test declares its topic and current affairs window in advance.
Difficulty
Calibrated to the observed range of the 2020 to 2026 papers. A question is hard because it demands reasoning or careful reading, never because it names something no reachable source contains.
Solutions
Each solution explains why the correct option is correct and why each incorrect option is not, with an all India rank, sectional accuracy and an attempt efficiency score for every test.
Errata
Published within 48 hours of each test, with marks revised where a question is withdrawn.
