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.
Generally a class is 3 credits. This means you'll have three hours of formal lecture a week (either one hour a day MWF or 90 minutes Tuesdays and Thursdays). A one credit course will have one hour of lecture a week (often seminars are 1 credit).
