Are you starting your senior year of HS? Can you take the class in the HS this coming year?
If I remember correctly you list classes you take senior year on the application. I expect health class is only important in that it is required for your HS diploma.
Also agree with @thumper1 that you should get a confirmation from your guidance counselor (in writing preferably) that the course you propose will count as the health requirement needed for graduation.
