just joined, in need of a reality check and frank advice about UT

Im currently a sophomore in HS, and as previously mentioned, seeking some brutal advice-givers about getting into UT. my freshman year I was top 10% of my class and had a pretty decent gpa, but with the work ethic I’ve had this year (if I could even call it that) I’ve managed to go down to 15% of my class… My EC’s are below mediocre, I’m president of my Latin club (taken four years) and I’m in tennis. I’m taking 5 AP classes next year, hoping that it will help my rank and gpa. Should I give up hope and just take dual credit next year or do I even have the slightest chance of being admitted? My one strength is test taking, the AP exams I’ve taken so far I’ve scored 4s, and I’m currently doing SAT prep at KD college prep. For the most veracious, I would appreciate your candor
