George, Your proposal is pertty good. The proposal is one thing, now we will start evaluation of student, basically check what you wrote in your application is true :) In the end google will not read your proposal, they will only look at the score we gave it to decide if you are accepted or not, so don't worry about the actual layout or possible typos in your application this is only one part of the equation.
