I like this idea. We already ask what environment students use. But I think the main focus of the application is to see if students are able understand their own project. We should ask questions that attempt to make this clear. My main question when I created this session idea was whether or not we should abandon, or at least refactor, the timeline portion of the application. On the one hand, it forces the student to think about exactly what they are going to do. On the other hand, it is never accurate (students always overestimate what they can complete in a given amount of time), and yet students still try to stress over making it accurate.

It sounds like a good idea, at least to match a strong programmer with a weak one, because we want to watch out for amateur mistakes, and give suggestions for things that the student probably would never think of (e.g., a more elegant object oriented or Pythonic approach to solving some problem). But on the other hand, I really think it's important to match students doing mathematically difficult (or even just theoretically difficult) projects with someone who knows as much about the theory as possible, because they are going to run into issues with the theory at some point, and it's nice when the mentor can give them help there. I remember there was a nice example of this with Ondrej and Sean. They can correct me on the details, but there was some issue with incorrect results. It was either an issue of a typo in a book or a typo in the code (I don't remember), but Ondrej helped him figure it out. The point it, you really had to know the physics to understand the problem and figure out how to fix it.

Backup mentors are helpful, especially for difficult projects. And of course, we will appreciate any help you can give reviewing applications.
