@ucbalumnus sort of brought up a good point that is related to this. You can get to medical school with an undergraduate GPA of 3.76. However, premed classes in university are going to be a lot tougher than high school classes. When you get to university, whenever that occurs, you are going to need to work very hard and make a strong effort to keep your grades up as much as you possibly can.
There are a lot of universities that are very good for premed students. An unweighted GPA of 3.76 in high school is pretty good, and will get you into a university with a good premed program. However, it does not strike confidence into me that you will be able to maintain a medical-school-worthy GPA in the tough university premed classes.
Right now job number 1 might be to be a good high school student. Part of this might be to get some sleep. Part of this might be to have some fun. Part of this is to learn how to do well in tough classes. Part of this is to get some background in biology, math, chemistry, physics, and other subjects in order to set a foundation that will help you do well after you get to university. All of this takes time.
