Wow, great question, Joey! I read your question, thought it was easy, started to reply, and then got immediately stuck on the word 收获。 XD In my English, I wouldn't say "收获" in that context, so I changed the words a bit. Below are a couple of ways I might ask your question: - What did you gain most at XX University? - What did you gain most during your time at XX University? If you want to be closer to the original, you can also say the following: - What did you gain most while studying at XX University? I'm sure there are many other, equally good ways to say it, as well. I hope that helps!
