Sections

In this book, you will find several headings that appear frequently (Time for action, What just happened?, Pop quiz, and Hero's trial).

To give clear instructions on how to complete a procedure or task, we use these sections as follows:

Time for Action

1. Step 1

2. Step 2

3. Step 3

Extra explanations are often required to break down instructions, so they are followed with:

What just happened?

This heading explains the working of tasks or instructions that you have just completed. You will also find some other learning aids in the book, including:

Pop Quiz – Heading

These are short multiple-choice questions intended to help you test your own understanding.

Hero's Trial – Heading

These practical challenges give you ideas for experimenting with what you have learned.
