- What high school classes should I take?
Take courses that are interesting to you! If right now you have an interest in math and science, take additional math a science electives. You don't have to limit yourself, however, to just math and science and should feel free to branch out and explore your interests.
- Do I need to take all AP/advanced classes?
You should take the most challenging course load that you can still succeed in. Colleges like to see students that push themselves and take advantages of the resources of their high school, so if you have AP options, you should try to take some of them. That said, don't take so many that you become overwhelmed and your grades drop.
- Is continuing volleyball a bad idea, or do you think it will help with coordination/stamina?
During high school, you should get involved with extracurriculars that you care about, because if you actually enjoy the activity, you're more likely to excel in it (i.e. win awards, get leadership positions, etc.) Your commitment and achievement within an extracurricular show colleges a lot about your values and character.
I wouldn't worry so much about whether volleyball improves coordination/stamina or not. You'll learn the physical acts of surgery if/when you're training to become a surgeon.
- If my school does not have a medical pathway, what is the next best pathway for me to look into?
For high school, just take science courses that interest you. For college, just about every 4 year university has basic life sciences departments within which you can complete your pre-med requirements.
- Is there anything I should do outside of school to further my education?
Use your first two years of high school to explore. Keep an open mind and join various clubs and organizations. This process may further convince you that becoming a surgeon is the right path for you, but it could also expose you to something completely different, and that's perfectly ok! As you move into your junior and senior years of high school, your interests will hopefully become a bit more clear and concrete, so during those two years, you should try to build depth in your areas of interest.
If possible, you can also do some shadowing. If you have family or friends who are doctors, ask to follow them at work for a day. You can also do this with other professions as well.
- Should I start to do volunteer work, if so what kinds of places?
Sure! Volunteering is a great way to become more familiar with what being a doctor actually looks likes. Many community hospitals have volunteer programs that allow high school students. Reach out to them and see if you can volunteer a few times a month. Another option could be volunteering at a nursing home. Often times, residents there are lonely and just want someone to talk to and you could really brighten someones day.
- What is a good way to study that works for you? (I have bad study skills)
Keeping your grades up is going to be important, whether you choose to be a surgeon or not. I suggest getting help before you're struggling. If, for example, you know you're not great a math, go to math office hours and review your assignments with your teacher. Get a tutor in the areas where you tend to struggle.
Something else that may be helpful is Improving your time management by cutting out things that distract you. For example, some people get distracted by their phone when studying. In that case, they might put their phone in another room when studying.
- How did you know that you had what it took to become a surgeon?
As you get more experiences in your science courses, shadowing, and volunteering, you'll get a better idea if the realities of being a doctor feel right to you. If it does feel right, then you can continue down the pathway to becoming one. If it doesn't, that's perfectly fine too, and you can pursue other avenues.
