Here is a suggestion:
For the MCAT, we do not really need to know the details of embryology. Usually, in those advanced classes of Developmental Biology or Embryology, they start the semester off with a brief overview of the whole subject.
Since the spring semester has just started, I would suggest you find out any Developmental Bio or Embryo class that is taught on your campus, and just sit in for the first 1 or 2 lectures. If the class is too big, you may not even have to tell the prof that you are gaining the free wisdom. If the class is too big, you may want to tell the prof your situation, and he or she would be happy to have you.
