..... I am not sure whether "Manual SLR" means just film or one without autofocus or something like that. "Manual SLR camera" means just a slr film camera, am I right?
Here is the test: "Does the camera still work after you remove the battery?"
If it does then it is a 100% manual camera. The shutter is spring driven with a clockwork. the film is advanced by a thumb lever and the user must rotate a ring to focus the lens.
You have two options (1) buy a new low-end 35mm SLR or (2) Get a used camera that was once a near top of the line. I'd say that if you can find a good used Nikon from a local camera shop get it. Get one new enough that it canuse AI-S lenses. But you need to buy locally. As for a lens, as a student you will want a 50mm lens.
The classic student camera is the Pentax K1000. You can pick these up dirt cheap (saw one for $20 the other day) but the quality does not approach that of a Nikon of the same age. I've taken a few apart, Nikon would use machined brass while the cheaper brands would have stamped sheet metal or plastic and now both cameras are selling 10 cents on the dollar.
You might want to use the camera after the class. Film camera can still do things digital can't. Buy a brand that has a large used market. Nikon is good that way, every camera store has a large selection of used Nikon gear. Just tell the guy at the store "50mm AI-S lens and a body to fit and then have him remove the battery and verift yhr film advance and shutter still work. (Of course the light meter will not work without a battery.)
