Can you also use opgenomen in the sense of to be admitted to the university, or is this verb only used to be admitted to hospital?
Among your options, I guess "Ik ben door de universiteit aanvaard" is the best one (note that "aanvaarden", while starting with "aan", is not a separable verb, and has a past participle without "ge-"). Not "aangenomen", and definitely not "opgenomen", which does indeed refer mostly to hospitals or psychiatric institutions. More colloquially, for competitive admission processes like that, people will often say "Ik ben binnengeraakt in ..." ("I managed to get into...").
