Everyone has to take either Con Law or Civ Pro after 1L. (then you take the other that fall) That summer you need at least two more credits--most people take an externship, usually in crim justice, other gov or public interest, or with a judge, which you get two credits for doing (technically there is also a "class" that goes along with it but it meets a handful of times over the summer and doesn't require actual work). The summer grade seems to not always come up during EIW because it takes professors FOREVER to get grades in--it will probably show up on your transcript by the time fall OCI rolls around, though. But assuming you don't totally screw up the summer course, and there really isn't any reason why you would assuming you did well the first year, switching from PT to FT will, based on the experiences of my classmates anyway, have zero impact on your prospects. My 1L year I went on eleven interviews and no one even asked about it.
