I'll tell you what I know from them cause they are my top choice as well and I called Samantha a few times to ask questions. As far as the GRE is concerned as long as writing is 3.0 that's fine, they don't weigh the writing portion that much, she didn't really tell me much more about the GRE though. I asked about job shadowing hours as well and she said "you are maxed out on points at 175 hours". So as long as you get 175 hours you have the max points for that category in your application. I don't know how they weigh anything else though. Hope this helps some! 🙂
