General Advice: To successfully transfer to an Earth Science program at a 4-year college, you will need to complete certain prerequisites, especially if you plan to graduate 2 years after entry to the 4-year college. TO BE ABSOLUTELY SURE THAT YOU ARE TAKING THE CORRECT CLASSES, you should research the programs you plan to transfer to and see what their freshmen and junior majors are required to take. Be sure to look at all the math, physics, chemistry, and biology requirements. These are the classes that you most want to take at City College. Unfortunately, most of your "fun" Earth Science classes should wait until you transfer.
B.S. vs B.A.
Some programs offer Bachelors of Sciences (B.S.) -- others Bachelors of Arts (B.A.). To find out exactly what each requires, you should check with school to which you are transferring. Generally speaking, the B.A. requires less math and physics than the B.S.
