No my friend has a GPA below 3. I don't know how far below, but I've heard that they usually are afraid to take on students that drop below 3.0.
The very high PCAT would make me look for extenuating circumstances if I was on the admissions committee. Did the applicant underestimate the difficulty of college courses at first? Did he initially have poor time management skills? Has the problem been corrected?
Upward trend is always a plus but UF certainly does not hold a one time exam over the body of work through years of classes. (Unless, the grades came from a questionable school or likewise, the grades came from their own school).
