FAQ
How should I use these programming fundamentals study resources?
Choose one foundation resource, one practice resource, and one review loop before opening more tabs.
Should I use free resources first?
Yes. Start with free resources until your error log shows a specific gap that needs a paid course, book, or tutor.
How do I avoid passive resource browsing?
Pair every resource with a timed sprint, a visible output, and a recap note before moving to the next item.
