SFSU Extended Learning Campus offers advanced autocad, which I took last year. I would have preferred to have taken it at Extension in hindsight. Because there was no required homework or assignments, I found I learned an overview of concepts and commands without getting comfortable actually using them. The credits don’t quite add up either to what you need, so I found myself taking a 1-day portfolio class to earn .5 units. It was helpful, but a little expensive at the end of the day.
