@Ohm888, I have to clarify:
For admissions purposes they cannot factor any courses planned in the summer, which is classified as part of the 2017-2018 academic year, toward the 2016-2017 admissions cycle. Taking them during summer will, of course, help, but the mere action of listing them as planned will not be considered.
Additionally, despite popular opinion, L&S CS is officially not capped and the department stance is that transfers are expected to declare by the end of their second semester here rather than the traditional first semester. There is no one semester deadline for declaration for L&S CS.
