Chem 1A and 2A are departmental course designations. This doesn't matter, only the actual title of course is what matters in order to be replaced. For example, I'm taking "general microbiology" at the CC to replace "microbiology" that I already took at my 4 year college. Notice, I didn't mention anything about it being called Micro 101 or Biol 119 because they are arbitrary registrar abbreviations. AACOMAS will look to replace based on its full title not the number after the prefix.
