These nine topics form the Mental Maths Olympiad syllabus for class 7:
Four of them were not on the Class 6 list: Number System, Square and Square Roots, Cube and Cube Roots, and Geometry, which returns after last appearing in Class 4. Knowing our numbers, Integers, Fractions and Decimals and Understanding Elementary Shapes are no longer on the list. Algebra, Comparing Quantities, Mensuration, Playing with Numbers and Data Handling and Symmetry continue from Class 6.
The prep guide adds detail such as rational numbers, simple equations, square roots of decimals, simple and compound interest, partnership, time and work, and the surface area and volume of cubes, cuboids, cylinders and cones.
The Class 7 paper keeps the Class 6 numbers. That means 100 questions and 120 marks in a single hour, with 80 Basique questions earning 1 mark and 20 Avance questions earning 2. Level 2 reuses that design and there are no minus marks for mistakes.
Each topic is broken down in the Class 7 topic breakdown.

Start by learning squares and cubes until they are automatic; squares up to 25 and cubes up to 15 is a sensible target.
Then work through Comparing Quantities, the longest part of the Class 7 prep guide: percentage, profit and loss, simple and compound interest, time and work, and time and distance. Learn one formula, then do twenty quick questions on it before moving to the next.
The class 7 Mental Maths sample papers show what that looks like in practice with 360 km at 60 km/h, a $20 book at 25% off, and the next term after 2, 3, 4, 9, 8, 27, 16. Try to answer each inside 36 seconds, which is the pace of the real paper.
