UT Austin Appeal, PLEASE HELP

I was rejected for admission for spring 2017, but I enrolled in a mini-semester class for the winter term. Should I explain that the transcript has not been sent yet?

Also, two classes I took in high school (dual credit) are killing my GPA (I would have a 3.5 without the courses). Should I also touch base on that?

Could anyone please offer some advice? I’m sorry if I seem out of wits.
