Free Mental Maths Olympiad Class 10 Study Material

Preparation Material of CREST Mental Maths Olympiad (CMMO) for Class 10

The Class 10 study material for the CREST Mental Maths Olympiad (CMMO) follows below, under the seven official Class 10 syllabus units from Number System to Data Handling. Each link opens a free CREST topic page, and the Comparing Quantities and Mensuration groups hold the most topics.

What's new in Class 10

Nothing is added. The official Class 10 syllabus has the same seven units as Class 9, and the paper pattern is the same. This guide is the Class 9 guide with three topics fewer: decimal expansion of rational numbers, and the surface area and volume of a hemisphere, are not listed for Class 10.

Class 10 also shares its CREST Mental Maths workbook with Class 9, as one combined book.

Class 10 paper at a glance

• One hour for 100 questions
• 120 marks: Basique 80 x 1 and Avance 20 x 2
• About 36 seconds per question
• Level 2 is set to the same pattern

How to use this guide in Class 10

• Put Algebra first. Polynomials and quadratic equations reward fast, careful work with signs and factors.
• Pair the Playing with Numbers topics, number series, alphanumeric series and factorisation, with Algebra, since they draw on the same pattern-spotting.
• Keep a single sheet of Mensuration formulas for cubes, cuboids, cylinders and cones, and of circle areas, and revise it before each practice set.
• Test each unit with the free Class 10 Mental Maths worksheets, then do the Class 10 CMMO sample paper under time.
