How to Use Free Resources Effectively
- Choose one resource per subject (avoid resource hopping)
- Complete courses (finishing matters)
- Take notes (active engagement)
- Apply immediately (projects, practice)
- Supplement with practice (resources teach, practice builds skill)
The resources exist. The question is whether you'll use them.
