Wow, that's really good for you! It's excellent that you feel motivated to accomplish your goals and turn your academic life around. A lot of people don't have a decent enough perspective on life to realize that what happens in school affects a person a lot in the future, and by the time they realize it, it's usually too late for them. I'm glad you're motivating yourself early, and I hope you get all the scholarships you need to succeed in college.
