Hey Ill be applying to UF myself pending my lsat in a month (excited

)
My gpa is borderline 3.0 (2.83 right now, hopefully with the 5 classes Im taking now it will rise)
My lsat preptests have been pretty consistent now... 166-168 still waiting for the 170 breakthrough and working hard on it.
I have 3 LOR's that Im planning on getting, 2 from my legal professors and one from my logic professor who's class I excelled in so hopefully he could write something exceptional!
I was thinking about swapping one letter (the weakest one) out for a LOR from my boss, Ive been working at starbucks for 2 years now on campus, for the sole reason that the job actually reimburses my tuition (depending on some stringent factors such as a minimum hourly work requirement by week, etc.)
All of my shitty grades have been in sciences or maths, and I have never gotten anything less than a B in all my legal/major related classes.
I am Colombian, and both my parents are from south america. While i was born and raised in miami, I was hoping to write a DS and an addendum explaining my grades, but im not sure a DS would help at UF considering the significant percentage of minorities in comparison to other schools.
**not to mention that im not even quite sure what my chances are with a "worst case scenario" 2.8 gpa and a 166 on the lsat.... I woudl most definitely retake in december if i do not reach at minimum the 168 mark.
