For goodness' sake slow down! I say this not as a [much] older person advising you to savor your fleeting youth -- though that's actually good advice. But rather, from an entirely pragmatic viewpoint of how best to get into medical school.
Right now, your rush to the finish has put you in a rather substantial hole. So STOP DIGGING!
Seriously.
You are now worse off application-wise than you would have been had you not hurried.
Why? Well, while you might save money and graduate sooner, you've been taking college classes -- which will count toward your final medical school application GPA no matter what you now do -- as a young high school student. Every college-level class you take counts toward your AMCAS GPA. That B you earned as a high school junior because you were competing against college sophomores? -- Yeah, you just shot yourself in the foot with that. Because instead of being 'excellent', you were merely 'good'. Now you'll have to make up for it, and the best way to do that is by spending more time as an undergraduate in college so you can dilute those B's with A's.
Since you're still a HS senior -- if you can DROP the dual-enrollment portion of some of your classes (anything you won't get an A in) - Do It! Take the class for high school credit only and forego the college credits. Again, for anything that isn't a safe A. Because all of those B's are going to diminish your admission chances much faster than your relative youth will enhance them.
Then when you get to college, do not try to rush through! You will be compared to students who have four years to accumulate leadership experiences, research, maturity, and yes, top GPAs, and right now, that comparison is not favorable to you. If you transfer in with two full years of credits, you're already halfway done, relatively immature, with minimal leadership and EC's and a sub-par GPA. If you were wanting to apply as a 'traditional' applicant (straight out of college), you're already virtually doomed.
Seriously.
Your best chance of improving your situation is by spending more time in college. (I know this is not what you or your parents want to hear, but listen carefully and do more research here to investigate whether what I'm saying is true or not. Do it soon.) Your best shot at medical school is to spend at least two more years in college before you apply. Plan to graduate in three (or even four) years instead of two. Retake your Bio or Chem and get the easy A's before moving on to upper level Bio and Chem classes. Take fewer credits each semester to assure you get exclusively A's -- you've got wiggle-room in the credits you need, so keep your coursework load light enough to assure success. Volunteer, do research, and get involved in a few meaningful activities. If you're doing any volunteering or medical-related activities now, keep at least one of them going in college so you can show continuity and dedication. Apply after you've got two stellar years of college grades (3.7+) behind you along with your ECs and volunteering.
If your motivations for spending only two years in college are financial rather than ego, realize that by not getting into medical school on your first attempt due to a poor undergraduate GPA, the most effective cure will still be -- more college. Or even more expensively, something called a 'Special Masters Program'. But neither of these is as good an option as simply spending more time in college.
I know this is not what you wanted to hear, but better to find out now...
