Not that great Honestly most of it is under subscription lock, and what is available has ads between 80% of these very short snippets of information that could be found online for free. For something titled a course, there are no tests. Youd get more if you bought a book. Only really good thing is how its organized.

Older version is better. The new version requires internet connection. Seafarers cannot access this while at sea. Too much ads.
