Get an introduction to optional challenges that reinforce the skills found in the course.
- [Instructor] This course includes several videos called Challenges. Challenges are quick activities that give you a hands-on opportunity to practice and master what you're learning. I'll start each Challenge by describing your core objectives for the activity. If the Challenge involves using any sample files I'll tell you where to find them. I'll also give you a rough estimate of how much time it took me to complete the Challenge. When you've completed a Challenge make sure to click the matching Solution Video. In each Solution I'll show you how I solved the Challenge and give you some of my thinking along the way.
Challenges are a fantastic opportunity for you to master what you've been learning. Have fun with them and reinforce your skills.
