First off, I was going to say I think it’s great that you’re inquiring early at the start of 10th grade year, when you can still can do a lot about your CV and overall application to BA/MD and BS/MD programs. Besides taking either the ACT or SAT eventually and doing as well as you possibly can; I would also plan on taking at least 2 SAT subject exams: 1 in a Math (usually Level 2) and 1 in a Science (Bio or Chem) – as many of the more competitive BS/MD programs do ask for SAT subject exam scores. The more competititive BA/MD or BS/MD programs tend to emphasize standardized test scores a lot, since they’re giving you potentially a medical school acceptance w/o an MCAT score and undergraduate GPA.
Continue to maintain and keep up your GPA and class rank as high as you can.
Some things I would suggest whether you end up doing so during the school year or in the summer:[ul][]Shadowing of actual physicians whether in a private practice or in a hospital so it’s clear you know what the life of a physician is actually like and not just based on a perception.
[]Participation in research, esp. undergraduate level or medical clinical research in some way (this is especially necessary for the more competitive BS/MD programs), especially if you can get your name as an author on a paper
[li]Taking part in other healthcare oriented activities that aren’t necessarily physician shadowing.[/ul][/li]You can get many ideas from posts from people who have put up their CVs on College Confidential.
Here are some books you can buy that I think will help elucidate the process of applying to BA/MD and BS/MD programs

So that’s a lot to put on your plate, but those are just some ways to flesh out your CV more which will help you regardless if you still decide to BS/MD programs or decide to go a very different route, whether in healthcare (Pharmacy, Dentistry, etc.) or not. If you have any further questions, feel free to ask.
