hmm. how difficult can it be? you go to the consultant, ask them if it's okay, and see 🙂 I don't think you have to go through trinity (although students might get upset if their spots are taken by non-trin students, but anyone who didn't get their act in gear and are only trying to get electives now deserves not getting their top choice). A&E is quite popular though. I'll pm you an email address for one of the AE consultants in SJH and you can try that, although it might take a little while for a response.
