the conditional-access corner — Coursera financial aid is case-by-case (apply per-course, ~16 days, not a guaranteed 100%) · edX audit is time-limited without graded work (transcripts downloadable where enabled) · Google/Udacity scholarships are eligibility-gated
the library unlock — many libraries subscribe to LinkedIn Learning: enter with your library card and the whole catalog is free (example) — check your local library!
myth-busts — Coursera “audit” is now preview-only · AWS training badges ≠ certification exams ($100–300) · freeCodeCamp = 6 checkpoint certs, not nine · LFS101 is Linux, LFC101 is not
the conference curricula — DEF CON media archive as a security-research path · PyCon talks via PyVideo as a Python masterclass path
─ the fine print, one line
free ≠ forever everywhere — free videos sometimes exclude labs/certs (DeepLearning.AI); follow each course’s own free tier and grab the downloadable notes
The tuition was always optional. Take the whole shelf.
