David is definitely right in saying you’ll need a lot more than 40 hours to become proficient in each of those programs, let alone the whole package.
It’s also true that the most valuable learning resources are actually free. I’ve taken a number of paid courses in cs and autocad and honestly…I would have learned more in the same amount of time sitting at home browsing something like tutsplus and trying to figure things out.
The best advice I can give you is to find something you personally enjoy, maybe digital painting or designing flyers for your friend’s band or whatever, then use self-directed learning and your own experimentation to work on it using whatever software works.
Also as a side-tip, be wary of blowing huge amounts of cash on studio supplies early in your course. A lot of my studio lecturers insisted on us buying quality art supplies which we never used, amounting to hundreds of dollars over the course of the degree. Some landscape architects benefit from these resources but I’ve seen work just as impressive done with a ballpoint on cheap paper.
