<p>I'm now a junior in high school maintaining a pretty good average this year ~95. In my previous years of high school, especially 10th grade, I didn't put much effort into certain classes and ruined my GPA. In 10th grade I had something like an 81 average overall.</p>
<p>I know that because my transcript will only be based on 9th-11th grades my poor performance in my previous years is going to ruin my GPA. I've heard that some schools allow you to retake courses and they will change your grade on record; however, my school does not offer such a thing. I've also heard that it's possible in some circumstances to take courses at local community colleges that would replace other courses that I in my previous years of high school. Has anyone heard of such a thing? If possible, it would be best if I could take these make up courses during summer vacation between 11th and 12th grade. Has anyone heard or done such a thing? If so what should I do to find out more information about this kind of thing?</p>
