[boost] GSoC2015

Hello, I wish to apply to the GSoC program, i have already read the wiki, and i'm currently working in a proposal. I just wanted to make a few questions as this is my first time applying for Boost Libraries and GSoC in general. First of all, i would like to know how much of a chance one gets as being "starter" working on boost. Second i would like to know if there is a way for someone to check out my proposal to see if i could improve anything, or should i just ask a teached in regards to that. And also i would like to know if any code i had already made in C++ is valid to be added to the proposal, or if there is anything else to improve your chances to be selected. Thanks for yor time.
