Linear Algebra and Summer Semesters?

[Frandroid]

Basically I want to try and see if I can do Linear Algebra in a summer semester next year (i.e. before the 2013 normal semesters start). When should I be able to enrol, and are there any requirements to do a summer semester? Does everyone get in or do you need some kind of alternative application or recommendations?

You enrol at the same time as you re-enrol for next year.  The pre-requisites are exactly the same as the normal semesters and along with your summer availability, those are the only requirements.
