I am a senior in high school right now, and here is my advise to you. If you truly have a passion for flying, then make the steps you need to take to fly your passion. If you are extra worried about Math and Physics, then put in a little extra work so you will do well. If you are really extra worried, get a tutor who can explain things well to you. This could be a friend who is really good at math and physics. It may be a good idea to pay them 5 or 10 dollars so you and your friend would be more serious about your learning sessions.

As for how I have done in school? I have done well, and that is only so because I worked hard. Try to maintain good grades the rest of the year, and especially your senior year. Colleges will want to see that you are doing well, or at least improving.

Lastly, when you get to flight school work hard. I think that it is possible to slack when it come's to ground instruction, but don't. Work hard! It makes the flying portion all the more fun. Good luck!
