Well what if you already for your associates degree in high school (ECHS) and and want to go to Harvard? What exactly are my chances? I have taken 64 hours of college credits. Would that count? Considering I want to be a cardiac surgeon?
Wanting to be a cardiac surgeon will not increase your chances of getting into Harvard. Your grades and board scores, EC’s , LoR, essays, and etc are what will get you into Harvard. So noone can tell you “exactly” what your chances are based on just the fact you have college credits.
While a few high schools across the country (Bard College High School in NYC among them) grant a college associate degree in high school, HYPSM will not accept college credits earned in high school UNLESS those credits are earned at the specific college a student is matriculating to. For example, Harvard WILL accept Harvard summer course credits taken by a high school student on Harvard’s campus, but they will NOT accept summer course credit taken from Yale, Stanford, Princeton or any other college. In addition, they won’t accept any college credits taken during your academic time in high school. Harvard used to address this issue on their website, but I can’t find it, so here’s this from Yale: https://admissions.yale.edu/faq/transfer-program
Harvard does have an Advanced Standing program for certain students who score well on AP tests
Which very very few students utilize.
Did you do dual enrollment? At a community college? If so, you might want to transfer to your state university for a cost-effective way to finish, and then look at Harvard for grad school. Often there at automatic transfers to a state U. (check your state) with benefits like early registration for community college transfers.
If you come from a family with income under $150k, you would pay 10%, and if under $65k, you would go to Harvard for free, so that is also a good financial option if it fits, but you would do the whole 4 years, not two, since your courses during high school would not count.
I wonder why you want to be a cardiac surgeon. That is a very specific career goal for someone your age. Make sure to plan for possible changes in your goals as time goes on. Many want medical school but many also change their minds 
People on this forum often advise against schools like Harvard for undergrad if you really do want medical school, because you will no doubt have a higher GPA elsewhere and apparently med schools care a lot about GPA in admissions.
Yup. FWIW, this website provides a glimpse into the GPA and MCAT scores needed for specific med schools: http://www.mcattestscores.com/usmedicalschoolsmcatscoresGPA.html
Thank you so much for the help
I want to be a cardiac surgeon because my ambition is to help and care people. I would like to help and save their lives
^^ That’s all well and good, but you can achieve that goal by attending any number of strong undergraduate universities, doing well in your pre-med studies and scoring a top MCAT score. So, why Harvard? What does Harvard offer you that cannot be obtained at say Yale, Princeton, Stanford, MIT, Amherst, Pomona, Georgetown, Duke, Williams etc?
FWIW: As your college GPA and MCAT score matter the most for top medical schools, you might actually be in a better position for med school by attending a less prestigious undergraduate school. Have you read this article: http://www.thecrimson.com/article/2013/9/26/the-real-premed-requirements/
Cardiac surgeons aren’t the only ones who help and save people’s lives. Many people have in their minds that Cardiac and Neurosurgeons are the epitome of being a physician, just like some would feel going to Harvard is the ultimate. You’re still young, and not even in college yet, and have absolutely no idea what you will want to do as the ultimate career goal. I remember wanting to be a cardiac surgeon also (since I too wanted to be the “ultimate doctor”), , but believe you me, you’ll be changing your mind so many times, since your future experiences will influence you to make more realistic choices that best fits your personality and skills.
Interventional radiologists, interventional cardiologists,
interventional pulmonologists, and even gastro-endoscopists continually narrow the scope of cardiothoracic surgeons
That is a really good point which I never thought about. Thank you so much for the consideration.
I don’t know about that. I mean ever since I started to learn about Biomedical, chemistry, and etc. It just has been my favorite subject. I am really good at chemistry and Bio med. But I hope I don’t change my mind later in the future. Right now I have no doubt in changing. Even though it may be hard but I am willing to try
