Hi dentdreams101,
If taken at Concordia, you may be able to take BIOL 225 AND BIOL 226 to fulfill the Mammalian Physiology option, without being in the exercise program, and I am under the impression that you may be able to take these courses as an independent student. As for fulfilling the molecular biology requirement, you have the option of either taking BIOL 261, BIOL 206, or BIOL 367. I am also fairly certain that BIOL 261 and BIOL 206 are open to independent students, but I know that BIOL 367 is only reserved for biology, chemistry, and neuroscience students. You may want to check with Concordia if you are willing to consider this route! Good luck!
