Current University is a free, self-paced course site. Lessons were drafted with AI assistance and are edited by a person; they can contain errors, so check anything that matters against a primary source. Current University is not an accredited institution and does not grant degrees, academic credit or, at present, certificates. Nothing here is medical, legal, financial, tax, career or investment advice.
