Chance Me / Match Me!

<p>Hi. I just want to know what are my chances to get in UCLA,USC, UMICH,UIUC,PURDUE etc.</p>

<p>I am taking the SAT in Dec cause my previous scores were terrible. I have given the suject tests and hope to get a good score.
The only thing is my school performance in 11th grade have been extremely terrible due to some reasons. My application won't be complete without those scores.
9th grade CGPA- 8.4
10th grade CGPA- 8.6
My high school teachers agree that I have improved in a year and I am currently doing better than my 11th grade. They also wish to mention this in the letters of recommendation. How can I manipulate my application such that I can explain them the reason for these scores. And will a good essay ,Sat ,subject scores help to ignore that ?
