Aptitude practice

Sit the paper before it sits you.

Timed mock tests across the categories placement rounds actually test. Fifteen minutes or thirty, one category or a random mix, and every question comes back afterwards with the correct answer and the working behind it.

How a mock works

Practise the way the real round runs.

The same pressure as the placement test, with a full review at the end so every mistake teaches you something.

  • On the clock

    20 questions in 15 minutes or 40 in 30. The timer keeps running, just like the real thing.

  • One topic or a mix

    Drill a weak category on its own, or take a random mix across all of them.

  • Worked answers after

    Every question comes back with the correct answer and the reasoning behind it.

  • Every attempt kept

    Your past papers stay in your history, so you can see your scores move.

Questions

Good to know.

Is it free?
The category list is open to everyone. Sitting a timed mock is part of the paid plan, from ₹499 a month, which also unlocks every course and the roadmap.
Is there negative marking?
No. A wrong answer scores the same as a skipped one, so it is worth attempting every question.
When do I see the answers?
As soon as you submit, or when the clock runs out. Each question shows your choice, the correct answer and the working.
Can I leave a mock and come back?
Yes, while its time lasts. The clock keeps running when you step away, and starting a new mock offers to take you back to the one in progress.

Sit one paper today.

15 minutes is enough to find out where you stand. The review afterwards tells you what to work on next.
