A course is considered to be a set of structured activities forming a guided learning path. Some courses offer free access, others require registration using an email address, while others still entail payment of a subscription fee (though often these provide free trials). In any case, almost all have freely available resources of some kind on offer, such as entry tests, link pages, etc.
