Chance me for Baylor University?

Ok I have several questions like what are my chances,and if I should do single choice early action?
At first I was planning to do the regular admission.But i read online about a students in a position like me with horrible test scores and grades.The student asked what were their chances to get into Baylor and many of course replied the students chances were slim and I’am fully aware of that.So they recommended to do the single choice early action because it gives a little bit more of a chance of getting accepted.Is this true?I wouldn’t mind this at all because I’m not planning to do early admissions to other colleges just regular because I’m still waiting for my ACT scores.My only hesitation is that I would be submitting my SAT scores which is VERY embarrassing and rock bottom horrible.I took the SAT three times and to be honest I feel very dumb and feel like I won’t follow my dream career since I was little but I’m going to try.My highest score was 500 in math 430 in writing and a 410 in critical reading.That’s why I’ve been very hesitant on all my applications because my scores are embarrassing.And today I just the ACT for the first time and I hope I did great,if not I plan on taking it one last time(I’m done taking the SAT taking it too many times look bad).Should I still do the single choice early action even with this horrible SAT score while I’m waiting on my ACT score (when maybe I could of done great).If I send this application

  1. will they let me superscore and resend my test scores?

2.Do you recommend doing this action?

I just don’t want my current scores to blow it all out and ruin my chances.
In addition I have a ok GPA its a 3.88 UW
I’m only in the second quarter (I go to a VERY competitive high school in a wealthy area with a lot of competitive asians and Indians who are very bright,so it’s really hard to rank and that’s all we talk about)
I’ve taken several PAP classes and unfortunately one AP class due to some complications in the past.I used to compete in dance my freshman and sophomore year and been involved in A lot of activities as for my JR. and Sr. year I’ve been VERY involved with my church and gaining a lot of volunteer hours and involved in organizations that serves third world countries I’m also looking foward to a Haiti mission trip next year in summer.And I’m still very involved in my school again.

  1. Also, I'm on the edge if it's worth my time to apply?

Because it’s almost impossible for me to get accepted. I mean I love Baylor and been dreaming of it but I strongly believe my scores are the buzz kill ,I’m not sure if I should pay and apply when I know their is a 90% chance of me being rejected.I’m not sure what do you think?
Sorry and Thank you for taking time to read this long page concerning of my application to Baylor and taking time to answer THANKS!
