Just be aware that distance classes can be incredibly difficult/problematic. I have completed 4 in the past year with three 4.0's and one 3.3 and I can honestly say each course took 2-3x the amount of effort of my on campus courses. There is, in my experience, very little guidance on what is important to study for the exams with everything in the text, and things not in the text and never covered in the course all fair game in exams. For example, in the course I earned a 3.3 (second highest grade in the class) every question I missed on every exam involved terms that were not in our text book or in any of the supplemental readings or in any of the optional texts (there weren't class notes or lectures.) In another course, the prof actually said, in lecture, that there wouln't be any questions about clotting factors. The video of the class was 3 years old. A 15 point question on our exam asked for a detailed explanation of all the biochemical processes and components of clotting. In the same class, one video had no sound, 3 were difficult to hear, and 2 had image issues (camera tilted so that all you saw was the floor.) Online/distance learning can be difficult.
Having said all that, it may be worth it to try. Other challenges I have experienced involve internet policy (if there is any sort of failure of your connection, it is your problem, even if it is in the middle of an exam, and even if the issue is with the school's server) so your grades/GPA are vulnerable to technology issues, and another challenge with some courses I considered were strict proctoring requirements (such as specific testing centers or admins of a local college, which weren't options for me.) So learn everything you can about the class before you sign up.
What have the reviews of your application revealed? Could volunteering with vet organizations like World vet help? Could getting a greater variety of experiences help? Greater animal experience?
upside down, it's not over till it's over!!
