High school grades. Is it possible to change them?

Well I am a sophomore in high school right now and I essentially ****** myself over last year and the beginning of this year. I got a 3.2 average GPA.

However in these last few months I have basically found my calling and that is to go to the air force academy, I have join the Civil Air Patrol, have extensively researched the Academy and I have decided that I will do absolutely whatever it takes to get in.

Is there any way that I can change those grades or some how improve my cumulative GPA beyond what the rest of Sophomore and Junior year will do?High school grades. Is it possible to change them?
It is only possible to change a grade if the teacher lets you do extra work and it has not become a matter of permanent record yet.High school grades. Is it possible to change them?
Short answer, no. Those were the grades you earned, and that's what you've got. You aren't the only one who wishes they could ';do over'; the start of high school. Concentrate on your studies from now on. Your junior year will count for more. Try to do honors or AP if that will weight your GPA more.
You can't change your previous grades, but you can up your averages by doing well in the coming years. Civil Air Patrol is a great place to prepare for the AF Academy if you devote some time to the program. Remember, over 10% of new students at the AF Academy are or have been CAP cadets. Got to some flight schools, national activities, and as many prestigious activities you can, excell in leadership, and advance quickly in rank!!!
