Why are you so intimidated to ask a direct question? One of the things that you will learn, as an independent college student, is that you’re on your own. To get answers, you need to be proactive and go to the source. Push your fear away to get what you need.
No one here can tell you exactly what you want, which is a “guarantee” that you’ll be admitted. That’s what you are asking us to give to you, and we can’t do that because we just don’t know the answer.
When you call, you can be very open with them and say, “This is the first time I’ve called. I am unsure what to do, and it’s kind of intimidating for me. Can you help me to figure out how to _____?”
In my experience, at a number of universities, they’ve been really good to me, my kids and former students, about taking calls.
