Hi! Good question. You are correct in thinking that you have to study science to go to medical school. Actually, there are specific classes you have to take to get into any med school. They are generally biology 1+ lab and biology 2 + lab, physics 1 + lab and physics 2 + lab, English 1 and English 2, general chemistry 1 + lab, general chemistry 2 + lab, organic chemistry 1 + lab and organic chemistry 2 + lab. The thing is, you can take these classes no matter what your major is. In college, you don't have to major in biology to take biology classes, and you don't have to be a science major to take any of these classes. It is a little easier to take all of these classes if they are part of your major curriculum. It is also more affordable to fit these classes in to your major. But, if you want to major in something totally unrelated to science, you can! And you can still take all of the required classes for medical school.
Let me know if you have more questions!
