at University - physical place - "university campus" in University - act of attending the University - you can be "in university" without actually being on the campus grounds. also - "Enrolled in University courses" location - "while he was at university..." act or experience - "he is enrolled in university..." Hope this helps.

If a speaker is asking about someone who is already within the grounds of the university, he would only say : She's in the university cafeteria/library/lecture hall etc If a speaker is talking about someone who is studying some distance away he would say : She's at the university of ............... and she's majoring in History.

The net is baddddddddddddddddd!!!! I will try to talk you!!!!!!!!!!.There are many people!!!!!!! In other timeeee byeeeeeeee and the answer: I think is better in university....at is used in relation to time..... Regards Leidy(real name.........dont forget !!!!!!!!!!!)

What the others have said is great. Don't get too worried about prepositions, though. It's one of the hardest parts of learning a language. At vs. in can be argued a lot, but for most places, they are, in fact, interchangeable. Ex. At/In the office, store, bank, school, university, etc.

Use AT for general locations and IN for specific rooms... at the university in classroom 202. At school in the library... In On At are the shortest but the most difficult prepositions to use because there are so many excpetions but experiences in real use will teach u how to use them correctly.
