Do you have Bio I and II done?? You will not be able to move on to higher bio classes without them.
Also, does your university offer pre-req/upper level classes during winters? The two universities I have been a student of offered only certain classes during winters, and pre-reqs/upper level classes were not among them. If it is the same case in your university, you have less time than you think, even if you plan to apply in 2014.
Considering you have 60 upper-level credits + around 32 pre-requisite credits, I would resign and focus on school ASAP because at 15-17 credits per semester, you would be on schedule to finish in two years (if there are no other road-blocks along the way) which would make you on track to apply in the summer of 2013 to matriculate in 2014.
Be sure to double check with an advisor.
