Yeah, I got special student status which allowed me to take grad level CS classes. Requirements:

* min 64 credits, 32 of which from HES, 12 of which must be in the relevant field, i.e. CompSci

* >= 3.33 GPA

* The hardest part: two recommendations, hence the value of building personal relationships with the professors.
