Med is possible without bio, but will make things easier if you take it from what I’ve heard. For med, the prerequisites are an English subject and chem. Many of the similar courses also require one of: methods, spesh or physics, so you’re well covered there.
As for which ones you should focus on most? Depends on your weakest subject, but also on your prereqs as their raw scores will be one of the criteria and getting your foundations down well will ease things later. English must be in your top 4 so I’d put a bit of emphasis there if you’re not great at it.
