Before you start
What you need to know before creating your path.
Can I create a path even if I do not know where to start?
Yes. Start with a simple goal, such as learning a new technology or preparing for an interview. Kognilo asks a few short questions to understand your starting point and prepare a proposal.
How long does it take to have a path ready?
You answer a few quick questions and receive a path to review.
Can I review the path before I start studying?
Yes. Before activating the path, you can review the proposal, understand the unit order, and decide what makes sense for you.
How do I know the content is trustworthy?
Kognilo prioritizes official and primary sources. Units and corrections retain verifiable references, and relevant disagreements are shown when they exist.
