A modern, student-focused learning platform for the entire Civil Services journey — guided courses, practice, spaced-repetition flashcards and daily current affairs, all mapped to the real UPSC syllabus.
Everything you do feeds one honest mastery score, from 0 to 100, that quietly fades as knowledge goes stale — so you always know exactly what to study next.
The idea
Most UPSC tools give you more to do. CortexLearn gives you one number you can trust.
One mastery score, mapped to the whole syllabus, and honest about what you have already begun to forget.
What it is
01
Flashcards · Spaced repetition
An Anki-grade SM-2 scheduler decides exactly when each fact should resurface, laid out as a path you can actually follow. You just study — the schedule does the remembering.

Practice · 4,500+ topics
Search any of 4,500+ slug-linked topics or browse by subject, then drill UPSC previous-year questions and MCQs with instant checking and a clear explanation for every option. Prelims or Mains, five questions or ten.

Decks · Subject by subject
Each subject arrives as a set of curated decks — Modern Indian History split into Twilight of the Mughals, the British Conquest, the Revolt of 1857 and more — so coverage feels like progress, not a mountain. The same spaced review keeps every unit fresh.

Coverage, recall and freshness roll into a single mastery score from 0 to 100, and seven ranks that mark the road to mastery.
67 collectible badges across 20 subjects and 47 areas, in four tiers — small, honest proof of the ground you have covered.
