UTGC

Technically, all the programs have to be "good" for prenatal, pediatric, and cancer because those are the three areas students have to be trained in per the ASGC/certifying board. But like @JN212 said, depending on what hospital(s) they run out of or do a lot of their rotations in, that can effect where they tend to concentrate more of their focus/where you will get more experience.

You don't even have to make a mention of waiting for another school. You can just say "Thank you so much, I'm really excited to get that offer. I'm taking some time to think today and I will be in touch when I reach a decision". They're very accustomed to students not immediately accepting an offer, it's the norm.
 
That said: if you get accepted by your 3rd ranked school and then get an offer from your 2nd ranked school, go ahead and call back school 3 ASAP and tell them you won't be accepting. You don't need to wait until you get in to your top choice to start turning down offers - only a better choice.

Just want to say that two of my classmates only had one interview and it clearly worked out for them!

I did a writing exercise for UT Houston so no guarantees it's the same sort of thing, but I bet it's not terribly different.
I was nervous about it too, but it's really nothing to be worried about - honestly it'll probably feel like a "break" from the actual interviews. At UT, they put us in a room by ourselves and we just answered some simple prompts. It was mostly situational and about interpersonal things (not quizzing you about genetics or anything similar), like "how would you respond if your supervisor told you XYZ?". In my experience, they definitely provided sufficient time to complete the exercise and I didn't feel like there were any difficult or trick questions. They just want to get to know you and this is another way for them to learn about how you think.
Feel free to send me a message if you have any more questions about how interviews are conducted!

I'd recommend emailing someone (whoever seems to be in charge of coordinating applications), I don't think you have much to lose. Just be sure it's phrased in a calm and professional way.
I think there may be some flexibility. One of my letters of rec writers didn't sign the letter she sent in and I had to get a signed version sent to a program after the deadline for receiving materials. It ended up fine and that's where I attend right now. At the end of the day, it's real - often compassionate and understanding - people who make these calls and no deadline is completely without any exceptions.

Emory just emailed me to invite me to an interview! I wasn't expecting to hear either way from anyone until the end of the month and am totally blown away. Ahhh! 

When picking schools to apply to, you may think that you'll be willing to go to absolutely any program that'll let you attend, but I ended up deciding after interviews that I wouldn't go to 2 out of my 7 schools even if they were the only option. I also turned down a 3rd school's offer to interview after some more thought. So out of 8 applications, I was only interested in 5 of those programs by the end.
I wish I had done more research before choosing where to apply. Two of them I could've easily nixed if I'd just taken a minute and asked myself "do you *really* see yourself being happy at that location?". Everything turned out well in the end, I just would've had a more pleasant application cycle if I had been more selective and didn't overestimate my level of desperation to just go *somewhere*.

Hey guys,
Just wanted to share this awesome and comprehensive spreadsheet with info about every program for those of you still trying to decide where to apply! (I didn't make this)

This may be frustrating, but there isn't a genetic counseling program ranking at all. The undergrad and med school ranking is pretty irrelevant, as the GC programs usually operate relatively independently. Therefore, you don't really need to consider Stanford more of a reach school than the other programs you've listed. It's Ivy League, sure, but when it comes to the GC program, I'm pretty sure they receive a similar number of applications as other desirable, established programs do (note: the number of applicants displayed on some program websites may be several years out of date, do not put too much stock into reported admission rates - they change quickly). And do remember: every accredited program gives the same degree and they all prepare you to do well on boards or they wouldn't be accredited. The closest thing you'll get to a ranking is perhaps to compare the pass rate for boards, but most were pretty high.
My tips for picking schools when the time comes is to focus on these elements (in no particular order):
Location/cost of living/tuition: Is this a city you see yourself enjoying? Can you afford this program in this location? How do you feel about the access to clinics for rotations - are you in a big medical center or do you have to commute a few hours to some of the sites? Rotation schedule: Are you the type of person that wants to jump into rotations in your second semester and learn by experience? Or do you prefer to wait for the summer when you might feel more confident and knowledgeable before seeing a patient? Pay attention to when rotations start as this is a pretty significant element of any program. Class structure: Are all of the classes GC only? Or do you take most of your classes alongside students in other programs, like a med school? Who teaches the classes - genetic counselors or doctors? Gut instinct: How did you feel about the program after your interview? Could you see yourself at this school? Did you like the program director and other staff? There are other things that are important, like the class schedule and way that research projects are handled, but it's difficult to make decisions based off of that when you're in the applicant stage, so don't worry about it if you're not sure what your ideal program would be in those areas.
Oh - and I think you're a very strong applicant. Good luck!

Just focusing on you post what are these "unearned advantages"? What exactly were you taught in these women's studies classes?

What's your undergrad degree in? I would read some critiques of Teach for America before deciding to go that route...

I think they are ranting about TAing/teaching whiny undergrads...

One thing I've heard of is that you can directly contact the Program Directors and ask where your application was lacking. It's part of their job, so don't be nervous!
I attended a "Career Camp" at Utah last month and the Program Director there talked about the admission's process. She did mention that sometimes it isn't about you, but about the other people they accepted that year. You could have been a stellar candidate, but they did not believed you'd click with the other applicants that they were interested in. She also said that someone who applied with basically the same experience would be passed over one year, but the top pick the next based on the interviewers and what they were looking for. A lot of things go into selecting who gets in and who doesn't that is really out of your hands.
She said that for reapplicants, they want you to take initiative for the next cycle, go get more experience, take additional classes, show that you still really want this!
I think it'd be best to ask the Program Directors for specifics, but you have two areas that you already see you could improve on, so I think starting there would be best! You can never have too much experience!
