You will have to visit an MVA office near you to register your antique or custom-built vehicle. Before visiting the MVA office, you will have to get the vehicle inspected at the MVA headquarters and obtain a VIN, if needed, for the vehicle.
Re: How Many Classes do College Professors Teach. For us (quarters, at least for a couple more years), it is 12. teaching units; usually, 3 courses of 4 hours each. Some of us have.
Typically 6-12 semester hours. Can be more if lab courses are included (in the US with most of my experience being in business schools). The actual number depends on the research requirements of the professor specifically or the institution generally. The more you produce in the way of respected academic journal research the less you are required to teach. This can be negotiated, esp. early in a career. The underlying assumption being that professors are either researchers or teachers.
