Hi, I got your DM but am answering here in case this information is useful for any other prospective McDermott applicants.
My son is a 2017 McDermott Scholar majoring in mathematics. It is a huge time commitment but one he has thoroughly enjoyed. He has truly loved the program and the opportunities it has afforded him.
The McDermott program does have a new director since his year and I can only give impressions from his class as I can’t actually say with certainty what will or will not make a student stand out.
For the application, you need a high GPA and test scores (yours are great!), a rigorous courseload of classes (I think you’re fine. I haven’t heard a specific number of APs being required. My son was IB so I don’t have personal experience there), a variety of ECs with leadership roles (my son’s were cross country, a civics club he co-founded, math team, playing piano at church and some musical theatre) strong volunteerism (I believe the average his year was 300 hours. It is important that your volunteer project be something you are passionate about not just something you are collecting hours for. (My son was a volunteer distance coach for a youth track team for three years)
For the essays, try to be creative when possible. You want to show who you are, not just what you’ve accomplished. Also, keep a copy of your essays. If you make it to finalist weekend, your interviewers will have studied your essays and your questions will be based in part on those answers. My son was taken aback when both interviewers asked about a self published novel he had written which was briefly mention in one essay and in his video.
In regards to the video, while not mandatory (although there was talk of making it mandatory I believe it’s still optional) treat it as mandatory. This is your big chance to show who you are. Avoid using the video to reiterate your accomplishments and use it as a way to introduce yourself. Most application videos are on youtube. Make sure to watch a variety of the videos done by previous scholars as well as some by those who did not make the cut. One of the staff members specifically mentioned my son’s video to him during finalists weekend so they do watch these!
Another thing we noted during finalist weekend is that while the program wants you to have a career in mind, they also want you to be open to other possibilities. Every parent I talked to whose child went in with a very specific college major/career path in mind got asked during interviews about what they would do if they found that they didn’t actually end up going in that direction. My son was able to run with the question as he does have a love of adventure and did address his tendency to try new things just for the fun of it, but another finalist was completely gobsmacked by the question and couldn’t answer and felt like she never quite recovered during that interview. While other factors could have been involved, she was not named a scholar. Also, FWIW, when he wrote the application my son wanted to be a high school physics teacher. Good thing he was open to other possibilities, as he changed to mathematics pretty early and is serious enough about whatever it is he’s doing (I am so not a math person!) to have just attended his first research conference - the only sophomore in attendance. So stay open to possibilities! If you are named a scholar, there will be many paths opened to you that you may not yet have explored.
As far as being OOS, yes it can be a plus. At least, it was for us.
If you have any other questions, I’ll do my best to answer them.
