How the categories work
Categories are derived from the topic tags on each course entry, so one course can sit in several. Every category page opens with an editorial note on how that field's courses differ — spreadsheet-first versus code-first data training, foundations versus project bootcamps in programming — because the platform tag alone rarely tells you which kind you are looking at. Ratings shown are verified on dates listed; blanks mean unverified, not zero.
