Translation:The students went to the exhibition at the same time as I did.
As an example, a collection of paintings by a painter that is shown at an art museum, would be a "выставка". I'd naturally use "exhibit" rather than "exhibition" for that in English, but more formally you might use "exhibition" (most museum websites use "exhibition".) The usage of "exhibit" is also possibly an American thing.
It's the same. I added it to our translations (thankfully, we do not have that many sentences with выставка).
