dSLR cameras are great and the way the future is going, but when you join in a school photography class, and it is a requirement to use a film camera such as has been mentioned in the OP, a dSLR would certainly not work at all compared to the "outdated" equipment of a film camera.Going into it thinking that you'll be able to use the outdated equipment you buy later on may not be realistic....
....Personally, I'd rather invest in an entry level dSLR (even if I had to save for a while)
Most photography courses require you to use a film camera. It takes away the "shoot 50000 shots and pick the best one" mentality that comes with digital. It forces the student to think about how they are shooting because they only have a limited supply of shots before they run out of film.
With film, you have to think about your settings and learn from the result good or bad while with digital, you can use every combination of settings and pick the right one after the fact. This is why they require in a photography class to have a film camera.
Its about learning, not about what is easiest to use.
