When a school requires a year of organic chemistry with lab does it mean that I can just take lab for one semester, and take the second semester without lab or does it mean both semesters need to be associated with lab? For example one school says 2 semesters chemistry with lab does it mean one lab or two labs? Also some schools say a certain amount of credit hours. One orgo class at my school is 3 credits; the lab is 2. If a school is requiring 8 credits of organic chemistry I could just take orgo 1 and 2 with one lab.
