There is an unusually high demand for CS 184 this semester!
Personally I am willing to let everybody who meets the requirement -- and is willing to do the work -- have a go in this course.
Thus it is crucial that you start to do the assignments immediately, if you want to have a chance to be enrolled in this course.
If you miss out on the first few assignments, I take this as a sign that you have decided to take CS184 in another semester.
Just in case that the attrition rate is not as high as it was in the past -- make sure you an alternative back-up plan!
The admission process should be concluded during the third week of the semester.
The CS enrollment policy is described in one of the CS Division Web
