About classnav

classnav is an independent, one-person site that helps career changers choose online courses — especially in AI, data and programming — without wasting money on the wrong one. It is run by a working professional who buys, takes and finishes courses the same way any reader would, then writes up what actually happened: the hours it took, the assignments, the certificate at the end, and whether it was worth the price.

Every review here is hands-on. The course is enrolled in and completed for real, with progress, graded assignments and study notes recorded along the way — nothing is reviewed from the sales page, the syllabus alone, or other people's reviews. When a course disappoints, the review says so, and each review includes a "who should skip this" section so you can rule options out as fast as you rule them in.

classnav is bilingual. This English edition is the main site; a Chinese edition, 课航， lives under /zh/ and serves Chinese-speaking readers. The two editions share the same underlying course notes, but every article is written separately for its own readers — not translated — because the questions differ: the Chinese edition digs into subtitles, payment and financial-aid mechanics, and how certificates are read by employers back home.
