How to prepare with a custom round

Ready-made math quiz competition sets are hard to find for your exact syllabus, and printable versions rarely match the topics your team has covered. DeckOwl builds a practice round from your own chapter notes or past problem sheets, with explanations you can review before the day.

Example math competition practice questions

What is the sum of the interior angles of a hexagon?720 degrees, because a hexagon splits into four triangles and each triangle contributes 180 degrees.

How many positive divisors does 36 have?9, because 36 = 2^2 x 3^2 and (2+1)(2+1) = 9 counts the divisors.

What is the remainder when 2^10 is divided by 7?2, because 2^3 = 8 leaves remainder 1 mod 7, so 2^9 leaves 1 and 2^10 leaves 2.

True or false: if a whole number is divisible by both 3 and 4, it is divisible by 12.True, because 3 and 4 share no common factors, so their product divides any number both divide.

In how many ways can 4 distinct books be arranged on a shelf?24, because 4! = 4 x 3 x 2 x 1 counts the orderings of four distinct items.

Short, regular sessions over several weeks work better than one long cram session. Review every missed question before attempting new material.
