I heard this in a talk on general productivity, but I can't find it right now.

The basic idea is, that if you are asked a question is not to respond to an individual directly, but a blog (or something similar), thus building up a knowledge base you can point people to.
Not having to answer the same questions over and over again already helps a lot and actually makes this interesting. There's only a limited amount of questions you'll be asked until you reach a point where you learn something yourself, because the questions are new to you.
Also this is potentially of help for the years after you and even other schools.

Maybe a forum is a better idea than a blog, because you wouldn't have to do all by yourself. In the beginning you would have motivated people pointing out duplicate questions and maybe someday even others will be able to provide answers.
Think of it as a homebrew version of stackoverflow, just for a specific group, possibly in your native language.

It's up to you to decide how far you will go. The fundamental step is to cut out the need to answer to the same stupid questions over and over again.
