A SIMPLE WAY IN

Look. Trace.
Understand.

Start with the visual. Follow the relationships. Then read the explanation to connect the picture to the computer science behind it.

01

Look at the whole

Notice the parts, labels, and overall shape before zooming into details.

02

Trace what changes

Follow arrows, branches, and states to see how the process unfolds.

03

Connect it to the course

Use the deeper explanation to review key terms and exam-level ideas.
