Hi there, I' Am a student at nova and just wanted to say congrats on applying to a great school : ) As far as the literature summary goes, just write it up basically like an abstract, but not as formal as a standard abstract. Does that make sense. I'm pretty sure they just want to see that you can read a fairly technical article and give a coherent summary of it. It wasn't brought up in my interview, or in any of my current classmates as far as I know of.
In regards to GPA and GRE, they're both parts of a whole application. Obviously if you are lacking in one, it'd be good to be above average in the other. But again, they're just a part of what it takes to get in. As long as you fall within their acceptable limits, I think they are just looking for people who they would feel comfortable working with down the road. Someone who is well rounded, sociable, and respectful. And apply ASAP! The earlier, the better.
