FYI- and this is just my two cents ( not directed at anyone ) : You can have mind-blowing stats and a BS can still think you’re not ready for this experience. Just sayin.
Maturity and readiness is more important than a fab SSAT score or an awesome EC. A lot of it has to do with how they see you fitting in… because YOUR comfort and well-being ( Thank God ) is paramount to everything else! I don’t want to be mean or hurt anyone’s feelings but I’ve seen way too many people gloss over that part ( when they’re waitlisted or rejected ) and blame other things … like a poor interview, not being athletic enough, etc. Oh, and my personal favorite: An unqualified legacy or athlete probably took my spot!!
Yeah, no- not even warm.
There are many tips for a new app cycle that I can give but here’s just a quick one to think about now : Showing interest in things that WILL make you a little uncomfortable ( see taking risks- which is actually a BS requirement ). Maybe you’ve never played a team sport before but the school offers something you’d like to try- Now we’re talking! Could you imagine a BS campus with a bunch of people who only do what they’re good at? Yeah- they can’t either because there wouldn’t be growth opportunities for anyone and without growth opportunities- Why bother? IMHO- a Key piece of a BS app ( which is often overlooked ) has more to do with what you haven’t done and what might scare the you know what out of you. It’s not about perfect stats, or a wonderful but boring list of accomplishments or about how you plan to continue these things in the future. YAWN. You and everyone else.
WHY do you want to go? Why BS? That’s the burning question. When my kids applied to BS, I encouraged them to look at what would challenge them the most and what would take them out of their comfort zone. AND- they also had to articulate WHY they chose the schools on their list… because if they couldn’t make their case to me ( I was tough and didn’t part with app fees easily )- How could they possibly make their case to admissions? Simply put: A successful BS app requires depth and a vision for the future. It doesn’t dwell on the past and it has to make sense.
If you weren’t accepted this time around maybe this is a good time to do a little soul-searching before you apply again. Branch out! You’re older and a little bit more wiser now. 
Two quick tips:
BS is a tough uphill slog every. single. day. even for incredibly motivated/ mature students with awesome survival skills. Choose the schools you apply to very carefully. One school does NOT fit all… so be very careful and do your research! Name recognition or prestige shouldn’t even factor into your decision. Period. Why? Because that’s really stupid and you’re not stupid. If you haven’t heard of Kent ( or any school in the Top 30-40 ) - that’s actually YOUR problem not theirs. It’s simply not enough to look at a school like Exeter ( as an example ) and say: Well, Mark Zuckerberg went here so it must be amazing ! Noooooo. It doesn’t work that way. That’s not a reason. Why is Exeter amazing for YOU and will your reasons for applying make sense to THEM? AND- How could you POSSIBLY KNOW IF YOU HAVE"NT COMPARED EXETER TO OTHER SCHOOLS??
Also- veering off a bit : Need Blind = Cattle Call. Ask yourself this question : Do you really, really love NB school ( for all the right reasons ) or are you cattle ? Have you considered the possibility that a NB school is highly selective because everyone and their pet hamster is applying because it’s NB? Being NB is truly an awesome thing but that doesn’t mean it’s the best school for you or the best BS out there. My God- and don’t be so quick to swoon… thoroughly research each and every BS and make them EARN you’re application.
I’m going to catch some flak for that one but I don’t care.
Look- all BSs in the Top 30-40 are truly amazing and ALL of them are in a position to offer students full or very generous FA. And- for FP students they’re worth every. single. penny.
There is no secret sauce for BS ( or college) admissions but I will tell you this: The universe usually rewards people who go in with an open mind and do proper research. If you’re applying again… I’d get going. 
Carry on and good luck.
