What Every Test Gives You
- 50 multiple choice questions framed only from that day's lesson - nothing outside it. 2,500 questions in total across all 50 tests.
- Every question in English and Tamil, so both mediums attempt the same paper.
- A full explanation for every question in the answer key, not just the correct option.
- The source PDF of the lesson, shared in advance, so you study first and attempt after.
- Your score and a question-by-question review the moment you submit.
Subjects Covered
All 50 lessons fall into six subject areas: History (வரலாறு), Polity (அரசியல்), Economics (பொருளாதாரம்), Geography (புவியியல்), Science (அறிவியல்) and Tamil Society (தமிழ்ச் சமூகம்).

Five Rules for the Fifty Days
- Read the source PDF fully before you attempt. Never guess your way through a lesson.
- Write the test on the day it is released if you can. Same-day practice teaches you the most.
- Read every explanation, including the ones you answered correctly - the explanation carries extra facts.
- Keep one notebook only for the facts you got wrong. Revise it every Sunday without fail.
- Complete all 50 tests. Steady work across 50 days beats a high score in any one test.
Every lesson PDF and answer key stays on the batch page through the series, so you can go back to any lesson while you revise.
