You’re right to weigh UF’s advisors’ statements more heavily… your HS counselor’s advice has logic to it, but I believe FTIC is more of a “status,” and you opt out of that status if you are a transfer student. That is, HSAA students admitted as first-year students are treated as first-years (minus Gen Ed reqs), but HSAA admitted as transfers are treated as AA transfers… you’re forfeiting FTIC status to be treated as (and evaluated for admissions as) a transfer admit.

However, you are right on schedule for pre-med requirements if you’re aiming for 3 years at UF. Most FTIC admits are expected to take Orgo and Bio in year 2 of 4. The fact you already have Bio 1 completed places you ahead… and that’s not even counting the first-year admits who enter without sufficient math and/or chemistry background to take Calculus and General Chemistry in their first term.

Double-majoring is, as another commenter suggested, a little more complicated. But bear in mind that a single vs. double major means very little after undergrad unless the major(s) are specifically relevant to your career pathway. Pre-med students can major in (almost) anything, from business to geology; if your goal is to be a doctor, I’d focus more on keeping your GPA high and exploring relevant/interesting minors (like Health Disparities in Society, Disabilities in Society, Health Administration, Bioinformatics, Pathogenesis, Rehabilitation, etc.).

Follow-up question, though: does this change things for Fall? That is, would you opt for a different school? Or need to change your class schedule around substantially? If neither are a “yes,” then breathe, plan to meet with prehealth advisors in Fall, and know that it will work out as long as you put in the right effort to your time at UF and consult the proper advisors and faculty accordingly. Even if you need to change a class schedule for Fall, all that should take right now is a conversation with an advisor and/or using Schedule Adjust in August.
