Before delving into further details, let’s take a moment to familiarize ourselves with the various diagrams that you may come across in the tests:
The questions related to the first two diagrams usually tend to be straightforward as they typically involve a smaller number of blocks or elements. However, as we move on to the other diagram types, the complexity increases, offering a wider range of possibilities for changes and variations. When working with these diagrams, it’s important to note that there are often several patterns of changes that can occur. It’s possible for multiple changes to happen simultaneously. Below are the common change patterns:
- Colour changes: from green to purple, or from green to purple then to white;
- Rotation: the most common pattern. A block rotates clockwise or counterclockwise;
- Motion: moves from bottom to top or vice versa. Sometimes you could see moves from top left corner to bottom right corner;
- Coloured blocks increasing or decreasing in a direction or rotation;
Let us take an example:
So we could see the internal block is “flashing” from green to white and then repeat while the external triangle rotates clockwise with colour changing. So the right answer for next image is:
