Accidentally purchased the wrong version for my class. (why there are two versions for the same thing is beyond me.) No way to get my $150 back even though I noticed it within 5 minutes. Seems to be just a good way for them to make money. So far the program has been terrible as well. Why teachers use this money stealing program is beyond me. If you can avoid it, but unfortunately like in my situation my class requires it so they go $300 from me.
