Chances of me getting into Clemson University

I am very interested in attending Clemson University, but I do not want to get my hopes up if I do not get in… I am from New Hampshire and really want to head south for a change. I have a 3.9 gpa, and I am ranked 145 out of 702 students, so basically I am in the 20% of my class.On my sat out of 1600 I have 1080, but I just took one last week hoping for my score to improve. On my ACT I got a 19, which I know is not the best and know I can do better. I am retaking the ACT at the end of this month. Also, I plan on applying to Clemson before Dec 1st, which is the priority deadline. As for clubs and activities I have been involved in enough to look good on my application.
some things I have been apart of is:
Sports:
Soccer- only my freshman year of high school
Activities:
2 years FBLA- future business leaders of America,which is a lot about volunteering and raising money for organizations
3 years of PALS- Volunteering with elementary students after school
Costa Rica Foreign Exchange- lived with a Costa Rican family for a week while attending a Costa Rican school for two weeks.
3 years of volunteering for a Community event hosted at my school for families
Possibly NHS, I applied this year but I will not know if I am accepted until the first week of November.

please let me know what you think, be brutally honest if you need to!

Clemson admits based on GPA, test scores, rank and rigor of classes. ECs are not weighed heavily at all. Right now your test scores will probably not be competitive for admission as the middle 50th percentile for SAT is 1170-1330 and ACT scores are 26-31 . My suggestion is to retake the ACT and/or SAT to get your scores up to be more competitive for admission. Clemson also admits to major with engineering , teaching and nursing being more competitive for admission. Clemson has gotten more competitive for admission over the past three years with over 21,000 applications and about half of those being accepted. OOS admissions are even more competitive . Good luck.
