<p>I will echo what virtually everyone else is saying. If it’s your Mom’s dream to be a doctor, then frankly, maybe SHE should consider applying to med school! If you have no enthusiasm for the idea at this early stage, it’s clearly not the path for you. Luckily, there are probably a dozen or more other good career options that are related to hard sciences in some way, and that will allow you to live a comfortable, well-rounded adult life with perhaps less stress than the medical school route would involve. I would simply recommend that you apply to large enough universities that you will have a wide choice of majors available to you once you are actually a college freshman/sophomore.
As ordinarylives said, just be sure to take general chemistry and general biology as a freshman and your options will remain open.</p>
