Reading is not enough for Prelims. You must know what to answer, what to skip, and when not to guess. CollectorX helps you practise these decisions.

Real UPSC questions. Clear explanations.

Verified PYQs

Questions from previous UPSC Civil Services Prelims papers.

Fair competition

Both aspirants receive the same questions and the same time.

06Questions before you begin

Clear answers, before your first duel.

What is Quick Duel?

Quick Duel matches you with an aspirant near your level. Both of you answer the same UPSC Prelims PYQs in the same order and within the same time. After the duel, you can compare the result and review every answer.

Are these real UPSC questions?

Yes. The questions come from previous UPSC Civil Services Prelims papers in publicly available official archives. They are scored against the answer keys published by UPSC.

How are marks calculated?

A correct answer gives you 2 marks, a wrong answer deducts 0.67 marks, and a skipped question gives 0. Speed does not add any extra marks.

What does my rating mean?

Your rating shows how you perform against other aspirants over time. Beating a stronger opponent increases it more. Losing to a weaker opponent reduces it more. Only the duel result changes your rating; fast tapping does not.

Can I practise alone?

Yes. Solo Practice lets you choose questions by subject, year, or topic. You can learn at your own pace or practise with actual Prelims marking without waiting for an opponent.

Do I need to pay?

Everything available on CollectorX today is free to use. If paid learning tools are added later, they will be explained clearly before you choose them.
