Higher Benchmark Test Revision — 6-topic bundle

You'll mainly deal with four number systems:
* Decimal (Base-10): The system we use daily, with digits 0-9. Each position is a power of 10.
* Binary (Base-2): Uses only 0s and 1s. Each position is a power of 2. This is what computers understand.
* Octal (Base-8): Uses digits 0-7. Each position is a power of 8. Less common now.
* Hexadecimal (Base-16): Uses digits 0-9 and letters A-F (A=10, B=11, ..., F=15). Each position is a power of 16. Used for memory addresses and color codes.

When we talk about statistics and probability, we're essentially dealing with data and the likelihood of things happening.

When we talk about Geometry and Measure, we're covering a lot of ground from basic shapes to complex calculations. It's essentially about understanding the properties of shapes and figures, and then applying formulas to calculate their sizes.
