I doubt anyone will ask. Some schools ask you to enter current and future coursework as a part of their secondaries, but not all. I took a couple pre-reqs during my senior year and didn't include them in my primary, and it was a non-issue. As long as you have the pre-reqs done by the time you matriculate, you're fine.
Prior to matriculation, the one med school to which you commit to enroll will require you to submit an original transcript from every school attended. Despite this impending "proof" of prerequisite fulfillment, some med schools reach out to ask an acceptee ahead of time their plan to complete the requirements.
