Ok first the bad then the good.
A) Yes it's illegal.
B) I have CS4 (legally, I might add) and 1) it's totally worth the money. 2) During my time in art college, I needed Flash for a course in digital media. It strikes me as weird that your school would require you to purchase these programs. My college had them on all of the university computers. Whether you bought your own copy to work from the comfort of your own home was up to you. Anyway, here are 3 legal alternatives that will save you from legal issues and/or give you piece of mind from a moral standpoint:
1. Buy the programs. As long as you are enrolled in college, you qualify for Adobe's Student discount. All you need is a student ID. That's how I bought mine. You get something like 80% off the standard price. It'll still cost you a few hundred, but when it regularly retails for around $1000, it's not a bad deal. And that's for the whole creative suite. You can go program by program, but often times it'll cost more for three programs than it would for the entire suite. More bang for your buck, my friend.
2. Like Aylaine said, Adobe has 30 day trials on all of its products. That's how I got through my poor college days. My 30-day trial of Flash got me through the bulk of my digital media course. When that ran out and I'd saved the money, I bought CS4 and have been using it ever since.
3. See if they have the programs on the school computers, and use those. I'm sure your school has a computer lab...why not check it out?
Again, it seems really strange to me that a class, especially at the university level, would require you to spend that much money. If all else fails, I'd contact the university and ask if it's school policy that you
have to purchase those programs to take the course. Again, I took half a dozen art courses that required the Adobe Creative Suite, and I was
never required to actually buy the programs. They were on all of the computers in the computer lab where we took the course.
Good luck, and may college have mercy on your wallet
