What courses are needed to be a marine biologist the first semester?
Generally your first 2 years of college are for general education classes. Some departments allow you to take the first few classes in your major, but most don’t. Get your college catalog and look under your department to see what requirements they have. Check them off as you do them. Most colleges follow the tradition that the classes you have listed in your catalog are the courses for you until you graduate. The only thing is that you have to stay in continuous enrollment for that catalog to still apply. Check with your college to see if they do this.
