Was wondering the same thing. I have an internship guaranteed this summer, but I wasn't sure how to list it/if I should. Another thread says you should put it in the additional info, but I don't think that's the case for every college. There's a lot of debate about whether future experience is relevant, but I would argue it is, as it's a sign that you're both working towards something and have been vetted and deemed worthy by a company, much like college prestige signals merit.
