I am taking a cloud computing class. We each use our own account and have registered for some free educational aws credits that come with the student developer pack. I think teachers can also request credits as well since we get an extra $40 or so from the prof. Whenever a student accidentally leaves an m4xlarge on for a week, which happens occasionally, he just calls up amazon support, explains what happened, and usually they'll fix it up if it doesn't happen too often. If you go serverless though, it's probably not going to be an issue. I would be amazed if a student used more than $10 doing anything with lambda.
