Maestría = Master's, and Doctorado = Doctorate (PhD, MD, PsyD, JD, etc.) These are examples of graduate degrees. "Bachelor's" is what you earn after you complete a degree from a 4-year university. Usually, you need a bachelor's to start earning a master's or doctorate. You can also earn an "Associate's." This is what you earn after you complete a degree from a 2-year community college. It might help you get a job, but it isn't enough to go to graduate school (master's or doctorate school). Some people earn an associate's and then transfer their credit to a 4-year university to earn a bachelor's for cheaper. "Major" is the emphasis you have for your degree. So, if you get a B.S. (Bachelor's of Science) in chemistry, then your major was chemistry. If you get a PhD in psychology, then your major was psychology. But "major" is most commonly used to talk about undergraduate degrees (associate's or bachelor's). When you graduate from high school, all you get is a high school diploma. As Kendall mentioned, some high schools have partnerships with colleges to allow you to take college classes while you're in high school, but I don't think you'd be able to earn an entire bachelor's degree while also going to high school. To earn a bachelor's degree, you need to be a full-time student for 4-5 years. I don't think you could do that while going to high school. You might be able to earn an associate's degree while still in high school, if you work really hard.

You can graduate with bachelor's if you take college classes as well as your high school classes
