Prerequisite Tree

The certificate program I am taking at Algonquin College does not provide a prerequisite tree, but I have created one as I do not want to get myself down a path of having to wait for a certain course to be offered to be able to proceed with my studies - I also just like doing things like this.

grey = not taken, blue = enrolled/currently taking, purple = completed

As you can see, there is really only one bottle-neck and I have started going down that path as much as I can. I plan on venturing down the bottle-necked path once I have completed my upcoming photography based course as with the exception of PHO5599, this prerequisite path is heavily computer based and will bore me to death if I try to complete them all in one go.
