Thanks for the replies to my question. JD you've explained testing the film very well. I have a Canon EOS Rebel XS that can rewind the film before all of the film has been exposed and I can change the ISO of the camera while there is film inside of it. I will gladly pay the 1yr student subscription fee. I really got into film photography after taking a black and white photography class. While it's a community college, they have an extensive photography program with a darkroom, processing rooms, studios, and stuff to mount the pictures. But whats important is that they have very professional people who love photography teach the classes.
