How it works
Choose your learning goal
Choose your learning goal. The learning graph is broken down in a few paths to ensure you don't have to learn everything if your goal is more specific.
Identify your potential
Take a test to identify potential gaps in your knowledge and the level of your skills. Or start from scratch if you're not familiar with Java yet.
System recommend you theory and practice
Let the system recommend you theory and practice that will fill in those gaps.
Explore the graph anytime
Deep dive into different topics in Java and explore the graph on your own to get a better conceptual overview of Java and the connections between the topics.
